Question

Line T has a slope of -2/3. Line U has a slope of 2/3. Are line T and line U parallel, perpendicular, or neither.

Answer 1

neither

Explanation:

line T: m = -2/3

If line U was parallel to T it would have the same slope (-2/3)

If line U was perpendicular to T it would have a slope that is the negative reciprocal of the slope of line T (3/2)
