first you need to find the slope of he current equation by changing it to y=mx+b

3x-2y=9 subtract 3x from both sides

-2y=-3x+9 divide both sides by -2

y+3/2x-9/2 Your slope of the existing is 3/2 or 1 1/2

a perpendicular line has the opposite reciprocal slope so 3/2 would be -2/3

-3 is your y intercept. now you can make your equation

y=-2/3x-3
