The given equation has infinite solutions. Each point on the line is the solution. Which means, p and q can be found by solving.
(a) x=-5, y=p are the solutions of -x+2y=4. x=5, y=p are the other solutions.
(b) The graph is a straight line. Find two endpoints and join them.
(c) Just like a, we can find by solving. x=r, y=0.5 are the solutions.
