Question

I have no idea how to graph it. I got the C part that it’s 45 months of service but I’m not sure to how come up with values to graph

Answer 1

In order to graph the function, the slope will be 20 and the y-intercept will be at C=40, taking into account that the limit is x=50

to find the line join points (0,40) and the limit coordinate found through the equation

`\begin{gathered} C=40+20\cdot(50) \\ C=1040 \end{gathered}`

the other coordinate is (50,1040)

then, cross a line at x=25
