Question

Hello! Can someone check and see if these answers are correct? Thanks!

1.) If a line with slope of 1/2 is perpendicular to another line, then the slope of the other line is -2. TRUE or FALSE? (I choose True)

2.) If Segment QR || Segment TU and the slope of Segment TU is -3, then the slope of Segment QR is -3. TRUE or FALSE? (I choose True)

3.) The slope of the segment with endpoints (1, 5) and (-3, 1) is -1. TRUE or FALSE? ( I choose False)

Answer 1

m' = -1/m
m' = -1 /(1/2) = -2 correct

2. yes true

3. m = (1-5)/(-3-1) = -4/-4 = 1 so false

Answer 2

I agree with your choices
