Question

The lines below are perpendicular if the slope of the green line is 2/3 what is the slope do the red line

Answer 1

Hey there!

When we know the slope of the line and we want a perpendicular line, we follow a specific rule.

We use the opposite of the reciprocal of the slope given.

Therefore, slope of 3 would give -1/3, slope of 1/2 would be -2, and so on.

Therefore, if we were to have a slope of 2/3, we take the opposite of the reciprocal to get -3/2.

I don't think your answer is here. If the lines are perpendicular, that has to be the answer; but do let me know if I made a mistake and I'd be glad to talk to you about this problem :)

Hope this helps!
