Answer
A) Twice the slope
B) Same slope, different y-intercept
C) Jon's graph is linear but Jenny's is not continuous.
Work Step by Step
A) Since Jon earns twice the hourly rate, his graph will have twice as steep of a slope.
B) Since Jenny gets a bonus, her graph will be shifted up, but both graphs have the same slope since they earn the same hourly rate.
C) Jon earns an hourly rate, so his graph will be linear. Jenny is paid at the end of the week, so her graph will include a sudden spike at the end of the week.
