Ok, so we need to find the equation of the line. We have the slope and a point given to us. That means we need to use point-slope form.

$$y-y_{1}=m(x-x _{1})$$

Insert the point we have, and the slope.

$$y-0=2(x-4)$$


y-0=2x-8
y=2x-8-0
y=2x-8

Now graph the equation on a line, and see if any of the points are on the line.
