Question

Line AB has an equation of a line y = 5x − 2, and line DC has an equation of a line y = −5x − 2. These two lines are

parallel because the slopes of the lines are the same

perpendicular because the product of the slopes is −1

both representations of the same line

neither parallel nor perpendicular

Help please im stuck!!! I think its either a or c!!

Answer 1

D
Not a because they don't have same slope. One is 5 and the other -5
Not b because 5x-5 does not= -1
Not c because they aren't same line. They may have same y-intercept, but they have different slopes

Answer 2

Oh i see. Thank you!!

Answer 3

No problem
