Question

What is the slope of the line passing through (-3, 5) and (5, -3)?
slope = -1
slope = 0
slope = 1
no slope

Answer 1

Slope is the change in y over the change in x

Answer 2

Hint: Use this eq. (y2 - y1) = k(x2-x1)

Answer 3

where k is slope

Answer 4

the second one rite

Answer 5

nope...

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

Answer 6

So lets see:
Point 1: (-3, 5)
Point 2: (5, -3)

(-3 - 5) = k(5 - -3)

k = (-3 - 5)/(5 - -3)

Answer 7

Its basically the change in Y over the change in X. Your change in Y is the difference between the second and first Y coordinates( thus Y2 -Y1), and the change in X is the difference between the second and first X coordinates (X2 - X1).

Answer 8

-1

Answer 9

Yep, thats it
