2x-3y=-3

Explanation:

"the equation of a line in "color(blue)"standard form" is.

color(red)(bar(ul(|color(white)(2/2)color(black)(Ax+By=C)color(white)(2/2)|)))
where A is a positive integer and B, C are integers.

"rearrange "y=2/3x+1" into this form"

"multiply through by 3 to eliminate the fraction"

rArr3y=2x+3

"subtract 3y from both sides"

cancel(3y)cancel(-3y)=2x-3y+3

rArr0=2x-3y+3

"subtract 3 from both sides"

0-3=2x-3ycancel(+3)cancel(-3)

rArr2x-3y=-3larrcolor(red)" in standard form"

rArrA=2, B=-3" and "C=-3
