y=-3
slope of zero means the line is flat, horizontal with a constant y value
just set y equal to the y coordinate of the given point (4,-3). Ignore the x coordinate, 4. y=-3 is the equation with slope zero through (4,-3)
or
try doing the slope point form of a linear equation
(y- -3) = 0(x-4) = 0
y+3 =0
y =-3
