Understand why

↗

The boundary line is solid because the inequality includes equality. Since x can be less than or equal to -2, the points on the line x=−2x = -2 are part of the solution set.

Conditions: The inequality is non-strict (≤).; The boundary line is x=−2x = -2.

Understand why

↗

The region above y=−4y = -4 is shaded because the inequality y>−4y > -4 requires the y-coordinate to be greater than -4. On a standard coordinate plane, larger y-values are located above the horizontal line y=−4y = -4.

Conditions: The inequality restricts y.; The boundary is a horizontal line y=−4y = -4.

The boundary line is dashed because the inequality is strict. Since x is greater than 3 but not equal to 3, the points on the line x=3x = 3 are excluded from the solution set.

Conditions: The inequality is strict (>).; The boundary line is x=3x = 3.
