Which point is a solution of the inequality y>-3x+5?

• (-1, -3)

• (1, -1)

• (-2, 12)

• (-3, 5)

What best describes whether a point is a solution for an inequality?

• Plotted on the line

• Plotted off the line

• Found in the solution Set

• Found in the non - shaded region

I can identify solutions and non-solutions to the linear inequality (points (x, y) )

• Agree

• Disagree

• Yes

• No

• Yes, it is a solution.

• No, it is not a solution.

Click on ALL coordinates that are solutions to this system of inequalities:  

 $y\le x+1$  
 $y>-3x-2$  

• (0,0)

• (0,1)

• (0,-2)

• (-4,0)
