Which equation is of a line is parallel to -2x + 3y = 15
Marta_Voda [28]

y=\frac{2}{3} x is the required equation.

<u>Step-by-step explanation:</u>

Equation of line is given as, -2x + 3y = 15

Now we have to write the equation in y = mx+ b form, where m is the slope and b is the y- intercept.

So the above line can be written as,

3y = 2x+ 15

Dividing both sides by 3 we will get,

y=\frac{2}{3} x+\frac{15}{3}

y=\frac{2}{3} x+5 is the equation of the given line

If a line is parallel to the given line then its slope must be the same, so the equation of line parallel to the given line is,

y=\frac{2}{3} x is the required equation.
