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
