How do you find the slope of the line passing through the points (-4,7) and (-4,-9)?

Explanation:

Slope Formula

m = (y2-y1)/(x2-x1)

m = (-9-7)/(-4-(-4))

m = (-9-7)/(-4+4)

m = -16/0

We cannot divide by zero, so the slope is undefined.

All vertical lines have an undefined slope because any two points on this line will have x coordinates of the same value. Those x coordinates subtract to 0.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
