Question

How do you find the slope given `y= -9x`?

Answer 1

`m = (-9)/1 or -9`

Explanation:

Any equation which is in the form `y = mx + c` represents a straight line. The coefficient of the x-term is the slope (m).

In `y = -9x`, the slope is therefore -9.
It is easier to use it as a fraction because then we have the change in y-values and the change in the x-values.

`m = (-9)/1`
