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

Answer 3

I think its the last one, because they dont have the same slope and the equation does not equal -1

Answer 4

Very good.....

Answer 5

Determine if triangle XYZ with coordinates X (1, 1), Y (5, 6), and Z (6, 2) is a right triangle. Use evidence to support your claim. If it is not a right triangle, what changes can be made to make it a right triangle? Be specific.

Answer 6

2. Triangle ABC has been rotated 90° to create triangle DEF. Using the image below, prove that perpendicular lines have opposite and reciprocal slopes. You must show all of your work to receive credit.

Answer 7

Actually perpendicular lines have negative inverse slopes...example..A line with a slope of -5 would be perpendicular to a line with a 1/5 slope.

Answer 8

oh, okay thank you:)
