    I assume you have a list of ordered pairs..?

    Ok, so these are all (x, y) pairs. What you need to do is plug them in to the two equations and check where they match. For example, the first ordered pair is (0, 8). That means: x = 0 y = 8 With your equations: y < 3/4 x + 3 8 < 3/4 (0) + 3 8 < 0 + 3 8 < 3 and y > 3/4 x - 1 8 > 3/4 (0) - 1 8 > 0 - 1 8 > -1 Only one of those is true (8 is not less than 3, though 8 is greater than -1), so this ordered pair is not a solution to the system. You can do this with the other two ordered pairs to figure out whether those are solutions to the system.
