Question

The function y = 50x describes the distance Gary has traveled in miles after x hours. Use the graph to estimate how many miles Gary will travel in 8 hours.

Answer 1

Substitute 8 for x in the function.
y=50(8)=400
He would travel 400 miles

Answer 2

We know that the equation is y = 50x and that x is the hours, since we need to know how many miles Gary will travel in 8 hrs plug 8 in for x and solve.

y = 50*8

y = 400

In 8 hrs Gary will travel 400 mi
