Question

Does anyone know what this is

Answer 1

`m = -3`

Explanation:

-To determine the slope of the red line on the graph, you need the slope formula:

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

-Since the red line shows it's decreasing, then the number will be negative. So, l picked
`(0,3)` and
`(1,0)` for the slope formula:

`m = (0 - 3)/(1 - 0)`

Then, solve:

`m = (0 - 3)/(1 - 0)`

`m = (-3)/(1)`

`m = -3`

so, the slope is
`-3`.

Answer 2

c

Explanation:

they have to have the same slope to be parallel
