Below are sample questions representative of the exercises included on this worksheet and related ALG2.51 Two Variable Linear Inequalities and Regions skill assessments:

Problem 1Difficulty: Mastery

A region excludes points on y = 2x - 1 but includes points on y = -x + 6. Which statement about the boundaries is correct?

AThe first boundary is dashed and the second is solid.

BThe first boundary is solid and the second is dashed.

CBoth boundaries are dashed.

DBoth boundaries are solid.

Solution & Explanation:Excluding points on a boundary means a dashed line, while including boundary points means a solid line.

Problem 2Difficulty: Mastery

How many integer ordered pairs satisfy x >= 2, y >= 0, and x + y <= 5?

Solution & Explanation:Count by x-value: if x = 2, y can be 0 through 3; if x = 3, y can be 0 through 2; if x = 4, y can be 0 or 1; if x = 5, y can be 0. That totals 10.

Problem 3Difficulty: Mastery

A tutoring center schedules x algebra sessions and y geometry sessions. It needs at least 18 total sessions, no more than 10 geometry sessions, and at least 4 more algebra sessions than geometry sessions. Which system models this?

Ax + y <= 18, y <= 10, x >= y + 4, x >= 0, y >= 0

Bx + y >= 18, y <= 10, x >= y + 4, x >= 0, y >= 0

Cx + y >= 18, y >= 10, x >= y + 4, x >= 0, y >= 0

Dx + y >= 18, y <= 10, x <= y + 4, x >= 0, y >= 0

Solution & Explanation:At least 18 total sessions gives x + y >= 18, no more than 10 geometry sessions gives y <= 10, and algebra at least 4 more than geometry gives x >= y + 4. Session counts are nonnegative.
