the lines graphed below are perpendicular. the slope of the red line is -2. what is the slope of the green line.

Question

texaschic101 · Answer

perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope and change the sign.

So if one line has a slope of 3/4, then its perpendicular line has a slope of -4/3 (see how I flipped the slope and changed the sign)

So what do you think the negative reciprocal for -2 is ? Remember that -2 is the same as -2/1

texaschic101 · Answer

so you have a slope that is -2/1...to find negative reciprocal, flip it and change the sign

anonymous · Answer

so the answer is -2

texaschic101 · Answer

no.....flip it and change the sign

-2/1....negative reciprocal is 1/2 (see how I flipped it and changed the sign

your perpendicular line will have a slope of 1/2
