Question

Help me with this please!!

Answer 1

-1.3

Explanation:

The graph shows the straight line passing through the points (3,-1) and (-3,7).

The slope of the line passing through the points
`(x_1,y_1)` and
`(x_2,y_2)` is

`(y_2-y_1)/(x_2-x_1)`

In your case, the slope is

`(7-(-1))/(-3-3)\\ \\=(7+1)/(-6)\\ \\=-(8)/(6)\\ \\=-(4)/(3)\\ \\\approx -1.3`

The rate of change is -1.3
