Solutions to Linear Inequality Systems

Which inequality is represented by the graph?

Choose all the possible solutions.

• Point A

• Point D

• Point F

• Point E

Which of the following points are NOT solutions?

• { C, E, B, J }

• { F, C, G, J }

• { D, H, J, G }

• { F, C, I, J }

Do the system of inequalities have solutions?

• YES

• NO

• Not Sure

• Solid because the inequality includes "equal to"

• Solid because it is "greater than"

• Dashed because the slope is negative

• Dashed because y-intercept is negative

This system has an infinite number of solutions, TRUE or FALSE?

• TRUE

• FALSE

Match the system to the graph (solution set is on the left)

• y ≤ 3x   and  y ≤ -2x + 4

• y > 3x   and  y > -2x + 4

• y < 3x   and  y > -2x + 3

• y > 3x   and  y < -2x + 4

Which of the following is not a solution to this system of inequalities?

• (0,-1)

• (0,3)

• (4,0)

• (6,-2)

Which system of linear inequalities is represented by the graph?

• y≤2x-1
  y>-2x+3

• y>2x-1
  y≤-2x+3

• y<2x-1
  y≥-2x+3

• y≤2x-1
  y>2x+3
