Answer:
The answer is 2.
2 since 6/4=3/2
Step-by-step explanation:
Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)
If y=kx then y/x=k.
So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.
So we are going to solve this proportion:

Again I put y/x from each point. They should have same ratio because this is a direct variation.
Cross multiply:


Divide boht sides by 6:


0.45M+40
The M stands for the amount of minutes he went over.
