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

Answer 2

Okay, have you graphed them?

Answer 3

They would be neither parallel or perpendicular because parallel lines would have the same slope. A perpendicular line's slope would be the negative reciprocal of the other line's slope. So for example in this question, one line's slope is 5 so a perpendicular line would have the -1/5. You basically invert the first slope.
