Same as the other type of problem, only this time you need to use the fact that perpendicular to means the same as "has a slope that is the negative reciprocal of" Finding the slope now requires rearranging the line the give you:
2x-3y=6
-3y=-2x%2B6
y=2%2F3x-2
Now you have your slope (m from the equation y=mx+b) as 2/3. But for your line, you want something that is perpendicular, or has a negative reciprocal slope. To find the negative reciprocal of a number, you take -1 and divide it by the number.
%28-1%29%2F%282%2F3%29=-3%2F2
So -3/2 will be the slope for your line, and again they give you a y-intercept (2). So putting that into slope-intercept format gives:
y=-3x%2F2%2B2
