Determine whether the following systems will have one solution no solution or infinitely solutions show algebraic process
1)
y=2x
y=2x+5
These have the same slope, so they're parallel.
No intersection, no solution.
--------
y=2x
y=x+x
This is one equation written 2 times.
--> an infinite # of solutions
