Answer:

see below

Step-by-step explanation:

We can check the slope and the y intercept.

Assuming these are linear equations

If the slopes are different, they will have 1 point of intersection  (one solution)

If the slopes are the same, we need to check the y intercept.

If the y intercept is the same, then the lines are the same  and the will have infinite solutions.

If the y intercepts are not the same, the lines are parallel, and they will never intersect and have no solutions.
