Which equation represents a proportional relationship? a
y =1 - 1/3x

b
y = 3x + 1/3

c
y = x+ 1/3

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.

Not entirely sure but entire negative number set? -1 -2 -3 -4 so on i have no idea
