Janie is walking in a walk-a-thon to earn money for charity. She walks at a constant rate and for every hour that she walks she
makes money. She models her earnings by a linear equation since she is walking at a constant rate. The x-axis shows the amount of time she walks in hours and the y-axis shows the amount of money she earns in tens of dollars. How much will she earn if she walks for four hours?
A) $4
B) $8
C) $40
D) $80
The slope of the graph is 2 units. So for every hour she walks she earns $20. The graph passes through the point (4,8) meaning if she walks for four hours she will earn $80 for charity sorry to say it but im pretty mad
off because of the answer sorry I mean the wrong answer on the bottom so i think everyone deserve to have the right one.
