Linear Inequalities

We will be able to match a linear equality with the graph and find solutions to linear inequalities.

I will be able to participate in the Quizizz lesson.

Finding solutions to linear inequalities

Remember any point in the shaded region is a solution and if it is a solid line then any of those points on the line are solutions.
Any point that is NOT in the shaded region is not a solution and if it is a dashed line then any point that is on the line is a not solution.

Multiple Choice

Are the points on the line part of the solution set or not?

Yes, they are part of the solution set

No, they are NOT part of the solution set

Multiple Choice

Choose the correct inequality for this graph.

Multiple Choice

Which of the following equations match the given graph?

y ≤ -5/4 x + 3

y ≥ -5/4 x + 3

y < -5/4 x + 3

y > -5/4 x + 3

Multiple Choice

Is the point (3, 1) a solution for the following inequality? Choose the best answer that has the best explanation.

Yes because it is located in the shaded region.

No because it is located on the line and the line is dotted.

Yes because it is located on the line.

No because it is in the shaded region.

Multiple Choice

Which of the following equations match the given graph?

y < 2/5x + 1

y ≥ -2/5x + 1

y ≤ 2/5x + 1

y ≥ -2/5x - 1

Multiple Choice

y < 5x + 1

y > 5x + 1

y ≤ 5x + 1

y ≥ 5x + 1

Multiple Choice

Will my line be solid?
5 ≥ x

Yes

Multiple Choice

Which point below is NOT part of the solution set?

(0, 0)

(-10, -10)

(-1, 5)

(5, 20)

Multiple Choice

How can I tell if an inequality will have a solid line?

It has an equal sign.

The symbol is greater than.

The symbol has "or equal to."

You just guess.

Multiple Choice

y < -x - 5

y > -x - 5

y ≤ -x - 5

y ≥ -x - 5
