Answer 1

Equations in the form y = mx+b are inconsistent when there are no solutions.

Put another way: if you have no solutions, then the lines must be parallel (or else they'd intersect to form a solution)

If you have an inconsistent system, then the y-intercepts of each line are different but the slopes are the same (to ensure you have two parallel lines that never cross)

Answer 2

Thank you !
