A line intersects the points (13,-4) and (1,12). Find the slope and simply completely

Answer 1

Let A (x1,y1) be (13,-4) and B (x2,y2) be (1,12). To find the slope, compute the change in the rise (delta y) over the change in the run (delta x):

(y2-y1)/(x2-x1) = [12-(-4)]/(1-13) = 16/(-12) = -16/12

Simplify: -4/3

Note: The order (the second coordinate minus the first or the other way around) is irrelevant, as long as you are consistent and use the same order for y and x.
