Front

When you graph an inequality, you use a solid line when you use which symbols?

Back

≤, ≥

Front

When graphing an inequality, you use a dotted line when you use which symbols?

Back

<, >

Front

Which point is a solution to the inequality? (0, 6), (-3, 4), (1, 0), (-4, 3)

Back

Front

What is a linear inequality?

Back

An inequality that involves a linear function and can be graphed on a coordinate plane.

Front

What does the symbol '>' represent in an inequality?

Back

It represents that the value on the left is greater than the value on the right.

Front

What does the symbol '<' represent in an inequality?

Back

It represents that the value on the left is less than the value on the right.

Front

What is the difference between a solid line and a dotted line in graphing inequalities?

Back

A solid line indicates that points on the line are included in the solution (≤, ≥), while a dotted line indicates they are not included (<, >).

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality; if it satisfies all inequalities, it is a solution.

Front

What is the graphical representation of the inequality y < 2x + 3?

Back

The area below the line y = 2x + 3, with a dotted line.
