Answer: Hello mate!
The line is described by y + 4 = 4(x - 3)
if we isolate y in the left side, we can write it as:
y = 4(x -3) - 4 = 4x - 12 - 4 = 4x - 16
this means that the points are of the form:
(x, y(x)) = (x, 4x - 16)
then, given the value of x, you can find the point that lies in the line; for example when x = 3, y = 4*3 - 16 = -4
then the point (3, - 4) lies on the line described by the given equation.
