(NO FAKE RIDICULOUS ANSWERS PLEASE! THIS IS URGENT!)What equation represents a line that is perpendicular to line MN?

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.
