Answer:

formula


m = (y2 - y1)/(x2 - x1)

Explanation:

choose two point of A, let k(-2, -3) and l(1, 3)


m = ( - 3 - 3)/( - 2 - 1) = ( - 6)/( - 3) = (1)/(2)

choose two point of B, let c(0, 5) and d(5, 0)


m = (5 - 0)/(0 - 5) = (5)/( - 5) = - 1

Hence the gradient of A is


(1)/(2)

and B is -1
