Question

Why is the gradient of line AB =1 and AD = -1 ?? PLS EXPLAINNNN URGENT THANKS

Answer 1

.It is because AB has a negative -3 while AD has only positives

Answer 2

Explanation:

gradient formula = y1 - y2 / x1 - x2

A = (3,0)

B = (0,-3)

C = (-3,0)

D = (0,3)

Line AB = -3-0/0-3 = -3/-3 = 1

Line AD = 3-0/0-3 = 3/-3 = -1
