Unit 2 Lesson 7 & 8

According to the graph, which of the following is the correct inequality?

Which inequality is graphed?

• A

• B

• C

• D

Which of the following is "NOT" a solution for the inequality?

y ≤ 5x - 1

• (0 , 3)

• (-2, -15 )

• (5, 24)

• ( 1, 7 )

Which of the following is true of the given graph?

y ≥ -2x + 1

• The graph is a dashed line, shaded above.

• The graph is a dashed line, shaded below.

• The graph is a solid line, shaded above.

• The graph is solid line, shaded below.

• A solid line

• A dashed line

If the inequality symbol is ≤ or ≥, the line will be

• A dashed line

• A solid line

Which inequality matches the graph?

• y < 3x - 2

• y > 3x -2

To use elimination method both equations must be in .......

• Slope Intercept Form

  y = mx + b

• Standard Form

  Ax + By = C

What does the bottom equation need to be multiplied by to eliminate your x values?

2x - 6y = 20

2x + 5y = -11

• -1

• 1

• 2

• -2

Using elimination method, what is the resulting combined equation for the system below?

9x + y = 12

-9x + y = 6

• y = 18

• 2y = 18

• -18x + 2y = 18

• -18x = 18
