Answer:
Option C.
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so
Find the value of the constant k
For the point (-8,-6)
For the point (12,9)
<u><em>Note</em></u> A single point was required to find the constant k (because the line passes through the origin)
The equation is equal to
