Answer 1

`m=0`

Explanation:

Given

See attachment

Required

Determine the slope of the line

From the attachment, we have the following points

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

and

`(x_2,y_2) = (3,1)`

The slope m is then calculated using:

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

Substitute values for the x's and y's

`m = (1-1)/(3 - (-4))`

`m = (1-1)/(3 +4)`

`m = (0)/(7)`

`m=0`

Hence, the slope is 0
