Question

I need the (rate of change____, so the rock is falling___meters per sec) (the initial value,the initial hight)

Answer 1

Answer:

- 6 m/s

Step-by-step explanation:

The rate of change is a measure of the slope and can be calculated using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 78) and (x₂, y₂ ) = (10, 30) ← 2 points on the line

m = $\frac{30-78}{10-2}$ = $\frac{-48}{8}$ = - 6

Rate of change is - 6 m/s
