If a line has an equation ax + by + c = 0, then its slope will be \\[ -(\\frac{a}{b}) \\]. Now the given equation of this line can easily be converted into the slope-intercept form, which we have discussed previously. The coefficient of the x-axis will be the slope of this line. Let us understand this better by using an example. If we are to obtain the slope of a line having an equation 5x - 6y + 11 = 0, then we can use the mentioned formula to determine the slope to be \\[ -(\\frac{5}{-6}) \\], which is 5/6.
