Which point is commonly used to test solutions in linear inequalities?

• (-1,-1)

• (0,0)

• (1,1)

• (2,2)

If the test point satisfies the inequality, which region should be shaded?

• Below the line

• Above the line

• Towards the test point

• Away from the test point

What is a system of linear inequalities?

• A single inequality

• Two or more equations

• A quadratic equation

• A polynomial equation

How do you find the solution to a system of linear inequalities?

• By solving each equation separately

• By finding the intersection of the lines

• By shading the non-overlapping regions

• By testing multiple points
