Question

Someone please help me?
Which is the correct classification of this system of equations?

-2x + y = 7
3y = 6x + 4
parallel

coincident

intersecting

Answer 1

I use this really cool online graphing calculator. If you type in the equations you can see if they are either parallel, coincident or intersecting.

Answer 2

if you can identify the slope, you can tell if they are parallel because they will have the same slope, if they dont have the same slope they are intersecting

Answer 3

if the equations are equal to each other then they are coincident
