Question

Find the slope of the sides of the following quadrilaterals.
A(0, 0), B(2, 4), C(5, 4), D(4, 0)
mAB =
mBC =
mCD =
mDA =

Answer 1

Slope is change in y over change in x. This means that you subtract the y coordinate of the first from the y coordinate of the second and the x coordinate of the first from the x coordinate of the second.

Answer 2

In the case of AB, (4-0)/(2-0)

Answer 3

BC would be (4-4)/(5-2)

Answer 4

Can you do the rest now?

Answer 5

yes thank you :)

Answer 6

Remember that you don't have to subtract the first from the second...you can subtract the second from the first. Either way you'll get the same answer...BUT make sure that if you choose the 2nd y to subtract from the first, you also pick the 2nd x to subtract from the first. You might try doing it both ways to see that you get the same answer.

Answer 7

So for AB, you could go (0-4)/(0-2) = -4/-2 = 2

Answer 8

for example
