line XY: 3x + 2y = -6, Z(3,2)

I realize that the slope of a perpendicular line is the opposite reciprocal of the first line. But, how do I use point Z in this problem? Thank you.

so the new slope will be 2/3

so then y=2/3 x+b

put point z into the equation, and solve for b.

**Reiny**, Monday, November 9, 2009 at 5:14pmSince you know that the slopes of perpendicular lines are opposite reciprocals, you should accept that the new equation must be

2x - 3y = c

plug in the point

6 - 4 = c = 2

so 2x - 3y = 2
