Question

Please could I have some help :)

Answer 1

Answer:

As shown in picture,

Line A passes (3, 3) and (4, 5)

=> Gradient of line A = (y2 - y1)/(x2 - x1) = (5 - 3)/(4 - 3) = 2

Line B passes (0, 4) and (4, 0)

=> Gradient of line B = (y2 - y1)/(x2 - x1) = (0 - 4)/(4 - 0) = -4/4 = -1

Hope this helps!
