Answer:
The maximum height is reached after 3.75 seconds.
Step-by-step explanation:
Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...
... 120 ft/s - (32 ft/s²)t = 0
... (120 ft/s)/(32 ft/s²) = t = 3.75 s
The ball will not go any higher after its vertical speed is zero.

Answers:
Slope = 3
y intercept = -20
=========================================
The two points (0,-5) and (1,-2) are on the line y = 3x-5. You can see this through a graph, or by plugging in x = 0 to get y = -5 (do the same for x = 1 to get y = -2). The point (0,-5) is the y intercept as this is where the graph crosses the y axis.
Multiply each coordinate of those two points by the scale factor 4
(0,-5) turns into (0,-20)
(1,-2) turns into (4,-8)
Find the slope of the line through the two new points (0,-20) and (4,-8). Use the slope formula.
m = (y2-y1)/(x2-x1)
m = (-8-(-20)/(4-0)
m = (-8+20)/(4-0)
m = 12/4
m = 3
Note how the slope we just found is the same as the slope of the original line. Dilations preserve slopes, so that means the image is parallel to the preimage.
Since (0,-5) became (0,-20), this means the y intercept is now b = -20
So m = 3 and b = -20 means y = mx+b becomes y = 3x-20. Plug in x = 4 and you'll find that y = -8; proving that (4,-8) is on the line y = 3x-20.
