Erin and her friends are taking a road trip. She has

agreed to drive between hours 3 and 6 of the trip. If h

represents the hours of the trip Erin will be driving, then h

2 3 and hs 6 represents her portion of the driving. While

she is driving, her distance and time are modeled by the

inequality d < 70h. What are the possible hours and

distances Erin could be driving?

A

When graphing this scenario, let h be the horizontal

variable and d be the vertical variable.

For the inequality h 23, the graph should be shaded

the boundary line.

For the inequality h s 6, the graph should be shaded

the boundary line.

For the inequality d < 70h, the graph should be

shaded

the boundary line.

One possible solution for Erin is
