since the answers all are 1-2x, we can assume that it will be '1-2x' and lets focus on the signs, the picture shows a solid line, when there is a solid line on a graph, which of the two answers you can cross out right away?

please think again, if it is a dashed line on the graph it means its not included thus u use >,< . but thats not the case for your graph. your graph has a solid line, which means included those points on the line, therefore which two are you going to cross out?

b and c

jim_thompson5910 · Answer

the boundary line is sold, so the inequality sign is ≤ or ≥

jim_thompson5910 · Answer

the shaded region is above the boundary line, so this means that the inequality sign is either > or ≥

jim_thompson5910 · Answer

> or ≥ means you shade above the boundary line

jim_thompson5910 · Answer

that's if y is fully isolated

cenaida · Answer

ooh so could it be B ?
