Question

What is the rate of change??

Answer 1

`-2 = m`

Explanation:

Starting from the origin, you do
`(rise)/(run)`by either moving two blocks north over one block west or two blocks south over one block east [west and south are negatives].

OR

`(-y_1 + y_2)/(-x_1 + x_2) = m`

[2, −4] and [−2, 4]

`(-4 - 4)/(2 + 2) = -(8)/(4) = -2`
