y = 23x - 1

Question

y = 23x - 2
one solution, no solution, infinite

Answer 1

There is no solution because the two equations have different constant values (-1 and -2).

Answer 2

are you sure that its no solution
y = 23x - 1

y = 23x - 2

Answer 3

I apologize, I misspoke. You are correct. The equations have the same slope (23), but different y-intercepts (-1 and -2). This means they are parallel lines and will never intersect, so there is no solution.
