Question: how to find the slope of a line if you know 2 points?
Answer: To determine the slope of a line passing through two points, we need to know the coordinates of 2 points on the line. Then the slope of the line is given by the quotient of the difference between the y-coordinates and the difference between the x-coordinates. i.e. slope = (y2 - y1) / (x2 - x1).
