Answer:
Gradient of line A = 4
Gradient of line B = -2
Step-by-step explanation:
To solve this question, we will use the formula for gradient passing through two points and
,
Gradient (m) =
For line A,
Since, line A passes through (3, 6) and (4, 10)
Gradient of line A =
= 4
For line B,
Since, line B passes through (1, 6) and (2, 4),
Gradient of line B =
= -2
