a Which part of the graph gives provides information about the initial registration fee?
B
b Which part of the equation tells provides information about the monthly fee?
A
a Yes, see solution.
B
b No, see solution.
Practice makes perfect
a The initial registration fee is paid at the beginning, when 0 months have passed. This is the y-intercept of the graph.
We can see above that the y-intercept of the line corresponding to Student B is greater than the one of Student A. This means that Student B paid a higher registration fee.
b A monthly fee is a consistent payment made every month. On the graph, this is represented by the slope of the line. A greater monthly fee means a greater slope and vice versa. We are told that the lines are parallel, which means they have the same slope.
m_A=m_B
Therefore, both students pay the same monthly fee.
