Graphing linear inequalities worksheet for Pre-Algebra
In Pre-Algebra a linear inequality is a line plus a region: draw the boundary from its slope and intercept, choose dashed or solid, then shade. Checking whether a single point is a solution comes up on its own, and it is the same test that picks the side to shade.
Also taught in Algebra 1 and Algebra 2, each at its own level and with its own examples.
Not quite the one you need? Same words, different skill:
- One-Step Inequalities (Pre-Algebra). One operation, including the negative that turns the sign round.
- Two-Step Inequalities (Pre-Algebra). Two operations, with negatives that flip the sign.
- Multi-Step Inequalities (Pre-Algebra). Like terms, both sides, parentheses, and word problems.
- Writing Inequalities from a Graph (Pre-Algebra). Read the circles and the direction.
- Quadratic Inequalities (Algebra 2). Where the parabola sits above or below zero.

How to do these
Is a solution of ?
- Substitute: 5 ≥ 2(2) + 1.
- The right side is 5, and 5 ≥ 5 is true.
The answer is Yes: is true.
Where students go wrong
Rejecting a point that sits on a solid line. For y ≥ 2x + 1 the line itself is included, so (2, 5), where both sides equal 5, counts as a solution.
Also called shading inequalities, half planes or graphing inequalities on a grid.
What you can put on this worksheet
- One inequality, shaded
- Graph → dashed line, shade above
- A fraction slope
- Graph → solid line, shade above
- A horizontal or vertical boundary
- Graph → Dashed horizontal line , shade above
- Is the point a solution?
- Is a solution of ? → No: is false
