I need help with a problem. Here it is: Find an equation of each line with the given slope that passes through the given point. Write the equation in the form Ax +By = C.
m = 3/2; (5,-6).

The answer I get is -3X+2y=-27. I know it is wrong. Please explain how I would solve the problem to get 3x-2y=27 instead.

Thanks much!
 
Those are the same. What's the dilemma?

Example. If you claim that x = -5, is that any different from claiming that -x = 5? No.

Your result is okay; however, many people define the general form Ax + By = C such that A is not a negative number. Perhaps, your text's author uses this definition. (Look up "general form" in the index, to begin searching for the author's definition.)

If you multiply both sides of your result by -1, the coefficient on x will be positive. 8-)
