Step-by-step explanation:

A: From your previous question you asked 14 hours ago with a screenshot, you did your graph wrong so for YOU make your graph look like the second image. (Plot the point 0,110 for the y intercept and plot -4.4,0 for the x line)

For C: you can answer in your own words since I gave you the priority answer(s)
