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 (5 points)

both representations of the same line
neither parallel nor perpendicular
parallel because the slopes of the lines are the same
perpendicular because the product of the slopes is -1

Answer 1

parallel lines have same slope
perpendicular lines have negative reciprocal slopes

y = 5x - 2 --- slope here is 5
y = -5x - 2 --- slope here is -5
not the same slope, not negative reciprocals, not the same line..
so what do you think ?

Answer 2

so,..is it b?
