Question

Calculate the slope of the line for Graph B.

Answer 1

-1

Explanation:

rise = -2

run = 2

Slope = rise / run

= -2/2 = -1

Since also the angle made by the line and x axis in anti clockwise direction is > 90° the slope will be-ve .

Answer 2

Slope = -1

Explanation:

You are provided with two points on the line (-5, 7) and (1,1).

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

`Slope = (7-1)/(-5-1) =(6)/(-6) =-1`
