When a cannonball is fired, the equation of its pathway can be modeled by h=-16t squared + 128t. find the time it will take for the cannonball to reach the ground.

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
