Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −2x+3y=12?
crimeas [40]

Answer:

I like to compare them all the same. Put all the equations in slope intercept form y=mx+b

So you need to isolate y.


Step-by-step explanation:

Main equation to compare y=2/3x + 4

If they have the same slope they are parallel. If they have opposite reciprocal slopes then they are perpendicular.


First one is y=2x +12 neither

Second one is y= -3/2x -1 perpendicular

Third one is y= 2/3x - 1 parallel

Forth one is y= 2/3x + 11/3 parallel
