I need help on this

Answer:
Your points should be at (0,3) (3,2)(6,1)
keep adding to the x value by 3 and the subtracting to the y value by 1 to get the rest and vice versa to get the higher ones
Step-by-step explanation:
You have to isolate that y variable first so
-6y = 2x - 18
divide by -6 on both sides
-6y/-6 = (2x/-6) - (18/-6)
y = - 2/6x + 3
simplify the slope ( -2/6x)
y = -1/3x + 3
