Question 754357
Are the two functions parallel, perpendicular, the same equation, or none of these choices?
Solve for y:
-x-3y= -18 --> y = (-1/3)x + 6
Slope = -1/3
-----------------
9x-3y= -27
3x - y = -9
y = 3x + 9
------------
Slope = 3
=============
The slopes are negative inverses --> perpendicular
