Question 59802
determine whether the graphs of the equations are parallel, perpendicular, or neither.
12.3y+2x=6
y=7-3x
Slopes are -2/3 and -3
neither
-------------------
13.2x-4y=3
3x-6y=8
slopes are 1/2 and 1/2
parallel
----------------
14.y+x=5
x-y=-4
slopes are -1 and 1
perpendicular
------------------
