Q: The slope of a line is defined by (Y2 - Y1)/(X2 - X1) where X and Y are the horizontal and vertical coordinates of points on the line. You must define two points on the line to calculate this formula. The point closer to the bottom of the line is (X1, Y1) and the point higher on the line, above the first point, is (X2, Y2). This formula can be restated as the rise over the run. It is the change in vertical difference over the change in horizontal difference, or the steepness of the line. If a line points upwards to the right, it will have a positive slope. If the line is downwards to the right, it will have a negative slope. A point on a line is given by the coordinate (X, Y) where X is the location on the horizontal axis and Y is the location on the vertical axis. To calculate the slope, you need to identify two points on each of the lines in question. Points are easily determined when you have a line drawn on graphing paper. To define a point, draw a dashed line up from the horizontal axis until it intersects the line. The position that you started the line on the horizontal axis is the X coordinate, while the Y coordinate is where the dashed line intersects the line on the vertical axis. For example: line l has the points (1, 5) and (-2, 4) while line r has the points (3, 3) and (1, -4). To actually calculate the slope, simply plug in the numbers, subtract, and then divide. Take care to plug in the coordinates to the proper X and Y value in the formula. To calculate the slope of line l: slope = (5 (-4))/(1 (-2)) Subtract: slope = 9/3 Divide: slope = 3 The slope of line r is: slope = (3 (-4))/(3 - 1) = 7/2 Remember, two lines are parallel only if they have identical slopes. Lines may look parallel on paper and may even be very close to parallel, but if their slopes are not exactly the same, they aren't parallel. In this example, 3 is not equal to 7/2, therefore, these two lines are not parallel.
A: Define the formula for slope. Identify the X and Y coordinates of two points on each line. Plug the points for each line into the slope formula. Compare the slopes of each line.

Q: Don't drag work home over the weekend if possible. The weekend should give you a break from work, not be a continuation of it. If you work over the weekend, your work weeks will run into each other, you'll start to experience burn out. Take a break to give yourself some time to regain your sanity. If you notice that you know more about your colleagues' lives than you do about your spouse's or friends' lives, you may be spending too much time at work. Take a step back, and commit to spending more time developing your relationships outside of work. One way to accomplish this goal is to ask if you can work from home one day a week. You'll at least cut down on your commuting time, giving you some more time with your family. The same holds true for school or for stay-at-home parents. You don't want your whole life to become school or your kids. You need your own life and sense of self outside of those parts of your life, despite how important they are. That is, go to bed early on Sunday night and make sure you ready yourself for the week ahead. You don't want to start the week by feeling tired or drowsy. You know it's important to have a sleep schedule; it lets your body know when to be ready for bed and when to get up. You may be tempted to skip the schedule on the weekends, but that only throws your body clock off and makes you drowsy come Monday morning. Try to go to sleep and get up at about the same time on the weekends. Whether it's a new necktie or a sparkly pair of earrings, choose something to wear on Monday that makes you perk up. Exercise will naturally boost your mood and has the added benefit of helping you sleep better.
A: Keep work at work. Don't let work affect your interactions with family and friends. Don't try to keep the weekend going. Don't ditch your sleep schedule. Put on something that makes you happy. Get your exercise.

Q: Replace the bolts, leaving them finger tight, allowing the assembly to move freely. Now you can tighten the bolts with your wrench, securing the strut assembly to the steering knuckle and torquing to the manufacturer's specifications. If you needed to move the sway bar or the brake line support, replace these at this time. Tighten the lug bolts finger tight before lowering the car. Jack the vehicle up slightly to remove the load on the jack stands, then remove the jack stands and lower the vehicle to the ground. Tighten the wheel to the proper specifications, as well as the strut tower bolts. Test drive at low speed to evaluate the vehicle safely. Avoid high speed driving or high-traffic areas. It's possible that the vehicle may require alignment. If the vehicle pulls to either side or otherwise does not drive normally, perform alignment by measuring the degree of difference and adding cams to adjust the issue. It's cheaper to replace struts on a need-to basis, but they tend to wear out all at once, so you might as well do the rest if you're willing to invest in two or four new struts. The process will work in the same basic way for struts in all positions. Not all cars have rear struts. Check your owner's manual before buying unnecessary parts.
A:
Install the completed strut assembly back into the steering knuckle. Place the strut assembly back into the strut tower and replace the strut tower bolts. Replace the wheel. Perform a final check to make sure nothing was incorrectly fitted. Repeat the process for all struts you want to change.
