A linear equation in slope-point form looks like this:
y -y0= m(x-x0)
Where m is the slope of the line and (x0,y0) is a point of the line.
In this case, we know that the slope of the line equals 4 and that the line goes through the point (1, -3), then, we can substitute these values into the general form to get:
y-(-3) = 4(x-(1))
