If two lines are parallel, they have the same slope
If two lines are perpendicular their slopes are negative reciprocals.

Perpendicular lines have opposite reciprocal slopes (so if one's 2, the quite a few is -2. If one's -5/3, the quite a few is 3/5, etc.) So first, enable's located that into slope intercept style: x/2 + y/3 = a million y/3 = -x/2 + a million y = -(3/2)x + 3 Now that each and every person persons understand the slope of the given line, all persons comprehend it fairly is perpendicular slope. m = 2/3
