See the graph. You would have to mark the point (4, -3) on the line y = -3

Explanation:

You have a point on the line and its slope. By the Point-Slope form, you may compute the equation of this line.

(y - y_1) = m(x - x_1)
implies (y - (-3)) = 0(x - 4)
implies y + 3 = 0
implies y = -3

Thus you must plot the line y= - 3 and mark(4, -3) on it. Only lines parallel to the x-axis have slope 0. Thus it is a line parallel to the x axis at a distance 3 from it in the negative direction.
