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.

Answer:

The solution of the system of equations is the point (-3,0)

Step-by-step explanation:

we have

-3x+y=9 -----> equation A

2x-y=-6 -----> equation B

Adds equation A and equation B

-3x+y=9\\2x-y=-6\\------\\-3x+2x=9-6\\-x=3\\x=-3

Find the value of y

-3(-3)+y=9

9+y=9

y=9-9=0

The solution of the system of equations is the point (-3,0)
