y-5=-\frac{1}{3}\left(x-3\right)
Fraction \frac{-1}{3} can be rewritten as -\frac{1}{3} by extracting the negative sign.
y-5=-\frac{1}{3}x+1
Use the distributive property to multiply -\frac{1}{3} by x-3.
-\frac{1}{3}x+1=y-5
Swap sides so that all variable terms are on the left hand side.
-\frac{1}{3}x=y-5-1
Subtract 1 from both sides.
-\frac{1}{3}x=y-6
Subtract 1 from -5 to get -6.
\frac{-\frac{1}{3}x}{-\frac{1}{3}}=\frac{y-6}{-\frac{1}{3}}
Multiply both sides by -3.
x=\frac{y-6}{-\frac{1}{3}}
Dividing by -\frac{1}{3} undoes the multiplication by -\frac{1}{3}.
x=18-3y
Divide y-6 by -\frac{1}{3} by multiplying y-6 by the reciprocal of -\frac{1}{3}.
y-5=-\frac{1}{3}\left(x-3\right)
Fraction \frac{-1}{3} can be rewritten as -\frac{1}{3} by extracting the negative sign.
y-5=-\frac{1}{3}x+1
Use the distributive property to multiply -\frac{1}{3} by x-3.
y=-\frac{1}{3}x+1+5
Add 5 to both sides.
y=-\frac{1}{3}x+6
Add 1 and 5 to get 6.
