The slope of the line that passes through (-9, -6) and (3, -9) is -1/4, the correct option is C.

How to find the slope?

If a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is given by the formula:

a = (y₂ - y₁)/(x₂ - x₁)

Here we have the points (-9, -6) and (3, -9), replacing that in the slope formula we will get:

a = (-9 + 6)/(3 + 9)

a = -3/12

a = -1/4

The correct option is C.
