Question

What is the slope of the line containing (-2, 5) and (4,-4)?

A. -2

B. 2

C. 3/2

D. -3/2

Answer 1

C -3/2

Explanation:

The slope is the change in y over the change in x. You find the change by subtracting

The y's are -4 and 5 (-2,5) (4,-4)

The x's are 4 and -2 (-2,5) (4,-4)

`(-4 -5)/(4 - -2)` =
`(-9)/(4+2)` Subtracting a negative is the same as adding a positive

`(-9)/(6)` Divide the numerator and denominator by 3

`(-3)/(2)`
