Answer:
3. Quadratic
Step-by-step explanation:
Penny is falling under gravity
acceleration due to gravity is constant
Velocity is the integral of acceleration, which is linear
Displacement is the integral of velocity, which is quadratic
The slope is -4 over -5
Your equation should be y2-y1 over x2-x1. At first you will get -8 over -10 then you simplify and get -4 over -5
i think it would be 55
