The formula that can be used to find the slope of a line from two points (x1, y1) and (x2, y2) is:
Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction
In other words, you subtract the y-coordinate of the first point from the y-coordinate of the second point, and divide it by the difference between the x-coordinates of the two points.
So, the correct response is:
y2−y1
Start Fraction _____
x2−x1
