Question

What does the dashed line when graphing inequalities mean?

Answer 1

It means that it is either greater than or less than. If it is dashed, the symbol is either < or >. However, if it is a solid line it means that it is greater than or equal to or less than or equal to.

Dashed line = < or >

Solid line = ≤ or ≥

I hope this helps!

Answer 2

it means that there is no greater than or equal too, so if there isn't an equal too, then it is dashed. this is because if you do happen to have the equal too, then the solution could possibly be on that line so it is solid. sorry if that sounds confusing.

so pretty much
