Question

What is the slope of the line passing through the points (-1, 3) and (4, -7)?

A. 2

B. 3/4

C. -4/3

D. -2

Answer 1

D. -2

Explanation:

slope formula =
`(y_(2)-y_(1) \\ )/(x_(2) -x_(1) )`

(-1,3)

`x_(2), y_(2)`

(4,-7)

`x_(1), y_(1)`

Plug in the numbers into the formula now

`(3-(-7))/(-1-4)`

negative minus negative equals positive

`(10)/(-5)`

reduces to -2
