Question

Please classify the following equations as parallel, perpendicular, intersecting, or coinciding (same line):

y = 3x + 2

9x - 3y = -6

Answer 1

Intersecting

Explanation:

Parallel lines means it will have the same slope, and perpendicular means the slope will be it's reciprocal, so the slope would be 1/3 x instead of 9x. Conciding means it's the exact same equation, so the answer has to be intersecting.
