Answer 2

2

Explanation:

The rate of change is defined by
`(Rise)/(Run)` ,
`(y_(2) - y_(1) )/(x_(2)-x_(1))`. or
`(Delta y)/(Delta x)`.

For your question, the points are (0,4) and (2,8).

Plugging these points into the formula:

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

After calculations, you would end up with
`(4)/(2)` or 2.
