Is the line y = 3x – 7 parallel or perpendicular to 3x + 9y = 9? Explain your answer.

Mama L [17]

Answer:

perpendicular

Step-by-step explanation:

The slope of y = 3x - 7 is 3.

3x + 9y = 9 → 9y = -3x + 9 → y = -1/3 x + 1 so its slope is -1/3.

This means that they are perpendicular because the product of their slopes is -1.
