Line m has intercepts $(−7,0)$ and $(0,−2)$.

1. Find the equation of line m.

   Hint (a):

   You are given the $y$-intercept. Calculate the slope and write the equation.

2. Is the point $(49,−16)$ also on line m? How do you know?

   Hint (b):

   Substitute the given point into the equation you wrote in part (a). Do you get a true statement?
