Question

which inequality has a dashed boundary line when graphed?
$y > 3x + 1$
$y \leq 7x - 1$
$y \geq \frac{3}{5}x + 1$
$y \geq -\frac{1}{3}x + 1$

Explanation:

When graphing linear inequalities, a dashed boundary line is used when the inequality symbol is strict (either $>$ or $<$), meaning the points on the line itself are not included in the solution set. Inequalities with $\leq$, $\geq$ use solid lines as they include the boundary line points.

Answer:

A. $y > 3x + 1$
