How do you represent a situation where one quantity is greater than another using an inequality?

Back

You can represent it using the 'greater than' symbol (>), for example, if x is greater than y, it is written as x > y.

What is the general form of a linear inequality in one variable?

Back

The general form is ax + b > c, ax + b < c, ax + b ≥ c, or ax + b ≤ c, where a, b, and c are constants.

How do you solve a linear inequality?

Back

To solve a linear inequality, isolate the variable on one side of the inequality using inverse operations, similar to solving an equation.

What does it mean to graph a linear inequality on a number line?

Back

Graphing a linear inequality on a number line involves shading the region that represents all possible solutions, using an open circle for < or > and a closed circle for ≤ or ≥.

What is the difference between strict and non-strict inequalities?

Back

Strict inequalities (<, >) do not include the boundary point, while non-strict inequalities (≤, ≥) include the boundary point.

How can you check if a solution to an inequality is correct?

Back

You can check by substituting the solution back into the original inequality to see if it holds true.

What is a compound inequality?

Back

A compound inequality is formed when two inequalities are combined, typically using 'and' or 'or' to connect them.

How do you solve a compound inequality?

Back

To solve a compound inequality, solve each inequality separately and then combine the solutions, ensuring to consider the type of conjunction (and/or) used.

What is the significance of the slope in a linear inequality?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable, affecting the direction of the inequality.
