Question

Which solution set is graft on the number line

Answer 1

x < 1

Explanation:

an open circle means it contains no equal signs.....everything to the left is shaded....means it is less then

x < 1 (thats a less then sign only) ....no equal sign in there

Answer 2

x < 1

Explanation:

Open circle: < or >

Closed circle: ≤ or ≥

Shading to the left: < or ≤

Shading to the right: > or ≥

Therefore, as there is an open circle and shading to the left:

x < 1

(x is smaller than 1)
