What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, greater than or equal to, or less than or equal to the other.

How do you represent a situation with an inequality?

Back

You can represent a situation with an inequality by using symbols like >, <, ≥, or ≤ to show the relationship between two quantities.

Front

What does it mean for one quantity to be greater than another in an inequality?

Back

It means that the value of the first quantity is larger than the value of the second quantity.

Front

What is the solution to an inequality?

Back

The solution to an inequality is the set of all values that make the inequality true.

Front

How do you solve a simple inequality?

Back

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

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run between two points on the line.

Front

What does it mean for two lines to intersect?

Back

Two lines intersect when they cross each other at a point, which is the solution to the system of equations represented by the lines.

Front

How do you find the intersection point of two lines?

Back

To find the intersection point of two lines, solve the system of equations formed by the two lines simultaneously.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that are solved together.
