Answer 1

Line A: 4

Line B: -2

Explanation:

Line A

Pick any two points from the graph such as (2, -1) and (3, 3)

Use the gradient formula to calculate the gradient:

Change in y/change in x

-1 -3/2-3 = -4/-1 = 4

The gradient of line A is 4

Line B

(1, -1) and (0, 1)

-1 - 1/1 - 0 = -2/1 = -2

The gradient of line B is -2

Answer 2
