Answer:
y = (-1/3)x + 4
Explanation:
m = rise/run = y2 - y1 3 - 4 -1
----------- = -------- = ----
x2 - x1 3 - 0 3
y = mx + b
y = (-1/3)x + b
Pick either coordinate. For this, I'll pick (0, 4)
4 = (-1/3)(0) + b
4 = b
y = (-1/3)x + 4
If you are certain about M = (-5/6), then replace (-1/3) with (-5/6)
I hope this helps!
