Not 100% sure but I think it’s A
Hi again!
x² + 8x - 20 = 0
Factorize the left side
(x - 2)(x + 10) = 0
Then set factors equal to 0
x - 2 = 0 or x + 10 = 0
x = 0 + 2 or x = 0 - 10
x = 2 or x = -10
Always,I am here to help!
(3,5)....x1 = 3 and y1 = 5
(1,3)....x2 = 1 and y2 = 3
slope formula : (y2 - y1) / (x2 - x1)
slope = (3 - 5) / (1 - 3) = -2/-2 = 1 <== slope is 1
