Answer 3

the red line has a positive slope since it goes up as you move from left to right

Answer 4

also, if you have a slope of -2/3, to find the perpendicular slope, you flip the fraction and you flip the sign

Answer 5

You're close, remember that after you flip, you multiply by -1, so in your case: -2/3, flip to get -3/2, then multiply by -1 to get 3/2!

Answer 6

oh so it's 3/2 ? :)
