Question

Graph a slope 3x-9y=9,3y=x+12,2x-6y=12

Answer 1

`3x-9y=9` Equation


`-9y=-3x+9` Subtract 3x from both sides


`y= (1)/(3)x-1` Divide by -9 on both sides


`3x- 9( (1)/(3)x-1)=9` Plug in for y


`9=9` Distribute -9 into the ( ) and simplify


`3y=x+12` Equation


`y= (1)/(3)x+4` Divide by 3 on both sides


`3( (1)/(3)x+4)=x+12` Plug in for y


`x+12=x+12` Simplify


`2x-6y=12` Equation


`-6y=-2x+12` Subtract 2x from both sides


`y= (1)/(3)x-2` Divide by -6 on both sides


`2x-6( (1)/(3)x-2 )=12` plug in for y


`2x-2x+12=12` Distribute -6 into the ( )


`12=12` Simplify
