Question

What is the rate of change of the line on the graph

Answer 1

A. ¼

Explanation:

Rate of change (m) =
`(y_2 - y_1)/(x_2 - x_1)`

Using two points on the line, (4, 1) and (-4, -1), find the rate of change using the formula stated above:

Where,

`(4, 1) = (x_1, y_1)`

`(-4, -1) = (x_2, y_2)`

Plug in the values

Rate of change (m) =
`(-1 - 1)/(-4 - 4)`

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

=
`(1)/(4)`

Rate of change = ¼
