MATH 8- QUARTER 2-WEEK1-LINEAR INEQUALITIES

Which best describes the graph of linear equation?

• It is a line.

• It is a curve.

• It is a region of points bounded by a curve.

• It is a region of points bounded by a line.

The statement, “the sum of two numbers is at least 29” can be expressed as:

• x + y < 29

• x + y ≤ 29

• x + y > 29

• x + y ≥ 29

What condition/s reverses the direction of the inequality symbol in a linear

inequality?

• adding negative integers to both sides of the expression

• multiplying or dividing positive integers to both sides of the expression

• subtracting negative integers to both sides of the expression

• multiplying or dividing negative integers to both sides of the expression

Which of the following linear inequalities in two variables are in standard form ? (choose all that applies)

• y > 2x + 25

• 2x − 3y ≤ 25

• 5x + 2y ≥ 25

• x – 2y < 25

Madeline is multiplying the −3 to the linear inequality of two variables, 4x − 6y ≥ 5 his answer is −12x + 18y ≤ −15, is She right?

• Yes, because the product of the terms is correct and the inequality symbol does not change.

• Yes, because the product of the terms is correct and the direction of the inequality symbol is reversed.

• No, because multiplying a negative integer does not change the

  inequality symbol.

• No, because multiplying a negative integer reverses the direction of the inequality symbol.
