equation of the line that goes through the points (0, -2) and (-5, 3).

Aball is thrown from 4 feet off the ground with a vertical velocity of 30 feet per second. is the ball at its maximum height after 1 second?   write an equation to model the height of the ball: h = -16t 2 +  a0 t +  a1given the formula; h = (1/)*t^2 + 30*t + 4solutions: h = - 16t^2 + 30t + 4after 1 second the height ish = 18 ftthe maximum height is  h max = 4 - 30^2/(4*(-16))h max = 18.0625 ftthe ball is not its maximum height after 1 second because 18.0625 < > 18.
