Answer:
y = 85x

Explanation:

The function
y = ax+b has the rate of change
a.

It's easy to see that the points
(0, 0) and
(4, 300) belong to the graph.

Solve this system of equations:


\left \{ {{0=0a+b} \atop {300=4x+b}} \right.


\left \{ {{a=75} \atop {b=0}} \right.

The rate of change of the graph is
a = 75.

Only
y=85x has higher rate of change in the answer section.
