The only one I can thing of would be the Number 1
Answer:
y = 2
Step-by-step explanation:
y=2 every time you add 3 to x your adding 2 to the y
-3 + 3 = 0 and 3 + 2 = 5
0 + 3 = 3 and 5 + 2 = 7
Y - 1 = 4y - 2/3. Move the ys over to one side, +4y crosses over to become -4y,
and -1 crosses over the right side to become +1.
y -4y = -2/3 + 1
-3y = 1 - 2/3
-3y = 1/3 Divide both sides by -3.
-3y/-3 = (1/3) / -3.
y = 1/3 * -1/3
y = - 1/9
