Question

A construction crew is extending a highway sound barrier that is 13 miles long. The crew builds $\frac{1}{2}$ of a mile per week. Write an equation in slope -intercept form that represents the length y (in miles) of the barrier after x weeks.

Answer 1

Given,
A construction crew is extending a highway sound barrier that is 13 miles long.
The crew builds $\frac{1}{2}$of a mile per week.
y = mx + b
m = $\frac{1}{2}$
b = 13
y = $\frac{1}{2}$x + 13
