Concepts

When graphing the inequality $y < 3x + 1$ , what type of boundary line
should be drawn, and why?

Solid line — the boundary is included in the solution set.

Dashed line — the strict inequality $<$ means points on the boundary
do NOT satisfy the inequality.

Dashed line — all linear inequalities use dashed boundaries.

Solid line — the boundary is always solid unless the coefficient of
$x$ is negative.
