Rewrite the equation as 3y+13=x.
Subtract 13 from both sides of the equation.
Divide each term by 3 and simplify.
Divide each term in 3y=x-13 by 3.
Cancel the common factor of 3.
Cancel the common factor.
Divide y by 1.
Move the negative in front of the fraction.
The given equation y=x3-133 can not be written as y=kx2, so y doesn’t vary directly with x2.
