I am sorry, but I don't understand your approach! How does this match the answer?

For you to solve the line using line equation \(y=mx+c\) you need to find the values of both m and c.

You can solve them by putting points (-4, 0) and the mid point of (2, 9), and (2, 0) into \(y=mx+c\).

However that would make it unecessarily long. You can directly solve for the slope using the metod presented in the solution post by Carcass.
