Factoring, you have
  h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)

The ball hits the ground when h(t) = 0, so
  0 = -16(t -4)(t +2)
  t = 4 or -2

The positive solution is the one of interest.
  It will take 4 seconds for the ball to hit the ground.

Which is the equation of the line with a slope 3 and y intercept 5
Bess [88]
<h3>Option A</h3><h3>3x - y = -5 is the equation of the line with a slope 3 and y intercept 5</h3>

<em><u>Solution:</u></em>

<em><u>The slope intercept form of equation is given as:</u></em>

y = mx + c ------ eqn 1

Where,

m is the slope of line

c is the y intercept

From given,

slope = m = 3

y intercept = c = 5

<em><u>Substitute m = 3 and c = 5 in eqn 1</u></em>

y = 3x + 5

3x - y = -5

Thus the equation of line is found
