Answer 2

When you multiply the slope of 2 perpendicular lines, it equals to -1.

So it says that XY is perpendicular to AB

then:

\(\sf\large (Slope~of~XY) \times (Slope ~of~ AB)= -1\)

Answer 3

I still don't get it @TheSmartOne

Answer 4

They gave you the slope of XY is 1/8

They want to know the slope of AB....

Answer 5

And what don't you get? Be more specific....????
