Question

Ed’s rental charges a flat fee of $5 plus $2 per hour to rent a pair of skates. A. Write an equation to model the cost of renting skates, y, for x hours. B. Graph the equation. Label the y-intercept

Answer 1

The cost equation has a constant rate of change, so this is a line of the form:

y=mx+b, you are told that there is a flat fee of $5 and an hourly rate of $2 so

y=2x+5

The y-intercept (the value of y when x=0) is 5.  The point (0,5) on the line. 

Answer 2

Answer:

y=2x+5
