mmmmhhh?
Isn't the second equation the same as the first?
And how many points would satisfy the first?
So what do you think?

If you mean infinite not indinetly than the answer is C.
2xy1=0 subtract 2x from each side
y1 = 2x + 0 add 1 to each side
y = 2x + 1 multiply everything by 1
y = 2x1
The equations are equal, so the system has infinite solutions.
