Answer 1

how many lines are there?

Answer 2

@amistre64
Two?

Answer 3

actually yes ... one for each equation.

where do they cross at? or rather, at how many points are they the same at?

Answer 4

@amestre64
One?

Answer 5

if you take a green crayon and draw a line

then take a red crayon and draw a line exactly on top of the green line

at how many points is the green and red line touching each other?

Answer 6

hint: its more than 1

Answer 7

@amistre64
4 or 5, I think

Answer 8

its physically, only possible for line to meet in 3 ways:

never, at one point, or at every point (infinite points) ....

Answer 9

concurrent lines are a special kind of parallel; same slope, same intercepts, they are on top of one another.

Answer 10

reduce 4x -2y = -2 and what do you get ? Or just divide everything by 2 and what do you get ?

Answer 11

@amistre64
Thanks for your help!!!
I was able to finish the rest of my test and got 100%
XD

Answer 12

@texaschic101
If you divide everything by 2, you get : 4 = 2, 2 = 1, -2 = -1.
Right?
