Problema Solution
A carpenter has already shingled 21 garage roofs and is shingling roofs at a constant rate of 8 per week. Write an equation that models the number of garage roofs r, after t, weeks.

We can use slope intercept form to solve this.
That form is:
y = mx + b
Where m is the slope and b is the intercept.
In your case, the slope is 8 and the intercept is 24, so that makes the equation:
r = 8t + 24
