NEED ANSWER ASAP!! PLEASE AND THANK U SM

Answer 1

- 6 m/s

Explanation:

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

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

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

m =
`(30-78)/(10-2)` =
`(-48)/(8)` = - 6

Rate of change is - 6 m/s
