Question

What is the slope of the line through (-9, 6) and (-6, -9)? A/ ⅕ B/ 5 C/ -5 D/ -⅕

Answer 1

C

Explanation:

Calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (- 9, 6) and (x₂, y₂ ) = (- 6, - 9)

m =
`(-9-6)/(-6+9)` =
`(-15)/(3)` = - 5 → C

Answer 2

-5

Explanation:

We can find the slope between two points by using

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

= ( -9-6)/(-6 - -9)

=(-9-6)/( -6+9)

-15/3

-5
