Answer:

d) c = 4.20h

Step-by-step explanation:

$25.20 for 6 hours is a unit rate of 25.2/6 = 4.2, or $4.20/hour

$16.80 for 4 hours is a unit rate of 16.8/4 = 4.2, or $4.20/hour

The unit rate is the constant of proportionality which is the slope.

The linear function is

c = 4.20h

Answer: d) c = 4.20h
