Answer:

( 1, 0)

Explanation:

you know that the slope of the MN line is 1/4 and a slope perpendicular to that is -4/1 ( negative and reciprocal ). then you can either draw a line from point p with the slope -4/1 and fine the point ( 1, 0 ) or you can do it the harder way which is plug the numbers into y=mx+b with 0 being b because you know the x-axis answer will have a y value of 0. (-4=-4x+0) and x is 1.
