Answer:
y = -3x - 1/9
Explanation:
general formula I believe you are saying so y = mx+b
(8, -4) , (6, 2)
plug this into y2-y1/x2-x1
2 -(-4)/ 6-8 = 6/-2 = -3
-3 equals the slope
then plug into the next equation to find the y-int. (b)
2 = -3(6) + b
2/-18 = -18/-18 + b
-1/9 = b
y = -3x - 1/9
hope this helps :))
