Question

Please help me with this review sheet

Answer 1

B

Explanation:

When you simplify the second equation

-2y = 6x + 6

you divide both sides by -2

y = -3x - 3

notice equation 1's slope is 1/3 and equation 2's slope is -3, for the second, it is negative and a reciprocal of the first, that suggests they are perpendicular to one another.

Answer 2

Explanation:

-2y = 6x + 6

y = -3x - 3.

Since (1/3)(-3) = -1, the 2 lines are perpendicular to each other
