A cell phone data plan has a monthly charge of $30 and charges $15 for each
additional 10 gigabytes of data. The function below can be used to determine
the cost of the cell phone plan for any month. What are the rate of change and
initial value?
y = 15x + 30
A. The initial plan cost is the y-intercept of 30 and the rate of change is $15
for each additional 10 gigabytes.
B. The initial plan cost is the y-intercept of 10 and the rate of change is $15
for each additional 10 gigabytes.
C. The initial plan cost is the y-intercept of 10 and the rate of change is $30
for each additional 10 gigabytes.
D. The initial plan cost is the y-intercept of 15 and the rate of change is $30
for each additional 10 gigabytes
