Question

Which statement best explains the relationship between

lines AB and CD?
-They are parallel because their slopes are equal.
-They are parallel because their slopes are negative
reciprocals.
-They are not parallel because their slopes are not
equal.
-They are not parallel because their slopes are
negative reciprocals.

Answer 1

They are parallel because their slopes are equal.

Explanation:

Find the slope using the points indicated on each line

The slope of AB

m = rise/run = 6/8 = 3/4

The slope of CD

m = rise/run = 3/4

They are parallel because their slopes are equal.

Answer 2

they are parallel because their slopes are equal
