## anonymous one year ago Find the set of points that are part of a line that is perpendicular to the line y = ­-3x

1. jim_thompson5910

hint: original slope = a/b perpendicular slope = -b/a notice how I flipped the fraction and the sign

2. jim_thompson5910

example original slope: 2/7 perpendicular slope: -7/2

3. jdoe0001

what's the slope of $$\bf y = ­-3x?$$

@jim_thompson5910 Ah yeah so the reciprocal?

5. jim_thompson5910

the negative reciprocal

6. anonymous

Right, I see. Thank you!
