to put it bluntly, the answer is a line. what you have there is one equation with two unknowns (x and y). what you can do is define one unknown in terms of the other. usually they define y in terms of x (as in y = mx +b), so solving for y, you will get y = -x - 3. you can now choose any real number for x and get another real number for y.
for ex, if you let x = 0, then y will be -3 (y = -0 - 3), and if you let x = 1 then y will be -4(y = -1 - 3)
