Question

The lines below are perpendicular. If the green line has a slope of -, what is the slope of the red line? Enter your answer as an integer or a fraction in lowest terms.

Answer 1

perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope and change the sign.
Example : if you have a slope that is 3/4 and you want to find the perpendicular slope, just flip the slope 4/3 and change the sign -4/3.
3/4 and -4/3 are perpendicular.
So basically, you need to find the negative reciprocal of -2/3. So flip the slope and change the sign and what do you get ?

Answer 2

3/2? @texaschic101

Answer 3

@ganeshie8 help?am i right?

Answer 4

yes...perpendicular slope would be 3/2
