Linear Inequalities TWO Variables

Front

What type of line does the inequality x < 2 represent?

Back

Dashed, vertical line.

Front

What is the inequality for the line with a slope of -5 and a y-intercept of -3 that includes the line?

Back

y ≥ -5x - 3

Front

What is the inequality for the line with a slope of 2/3 and a y-intercept of -3 that does not include the line?

Back

y < 2/3x - 3

Front

Which inequality signs produce a solid line?

Back

≤ and ≥

Front

Which ordered pair is not a solution for the inequality 3x - 2y ≥ 15?

Back

(4, 5)

Front

What does a dashed line indicate in a graph of an inequality?

Back

The solutions do not include the boundary line.

Front

What does a solid line indicate in a graph of an inequality?

Back

The solutions include the boundary line.

Front

How do you graph the inequality y > 2x + 1?

Back

Graph the line y = 2x + 1 as dashed and shade above the line.

Front

How do you graph the inequality y ≤ -3x + 4?

Back

Graph the line y = -3x + 4 as solid and shade below the line.

Front

What is the slope-intercept form of a linear inequality?

Back

y < mx + b or y > mx + b, where m is the slope and b is the y-intercept.
