For each Y value to have more than one x value would be a linear function.
It would make a straight line.
70 ft per sec going upward 3 sec from 6 ft high should reach 216 ft, but unfortunately gravity is pulling it and at some point it starts to go backward (at 2.176 second), so to compensate the upward slowing down and distance dropped, use -32.176 times 3 square times 1/2 = -144.792 which is the natural drop distance if the football is released mid air without a initial speed after 3 seconds. 216 - 144.792 = 71.208 ft high.
First, you must find the slope, which is -5-4/-1-4, or 1.8, and then put it in point-slope form, or y-4=1.8(x-2), which simplifies to y-4=1.8x-3.6, and so put it in general/standard form, you have to subtract 1.8x from both sides and then add 4 to both sides, and lastly divide both sides of the equation by -1.8 to get x+y=1.889, or x+y=1.6/1.8.

Answer:
A = 64 units²
Step-by-step explanation:
A = 1/2bh
Step 1: Define
A = ?
b = 16 units
h = 8 units
Step 2: Substitute and Evaluate
A = 1/2(16 units)(8 units)
A = (8 units)(8 units)
A = 64 units²
