## Students will review:

This chapter helps students review the lessons in a Geometric Graphing Basics unit of a standard GMAT prep course. Topics covered include:

- Understanding what a number line represents
- Plotting points on a number line
- Identifying points on a coordinate plane

### 1. What Is a Number Line?

A number line is a visual representation of all real numbers. In this lesson, we'll learn how to identify points on a number line. We'll also practice addition and subtraction, letting the number line do all the hard work.

### 2. What Are the Different Parts of a Graph?

Being able to read a graph isn't just vital for an algebra class. Graphs and charts are used everywhere! We'll take a crash course on the basic x/y plane used in algebra and the fundamental vocab you need.

### 3. Plotting Points on the Coordinate Plane

If you'll be working with a graph, otherwise known as the coordinate plane, it's essential to understand how it works. This includes learning the parts of a graph, identifying points and plotting points.

### 4. End Point: Definition & Formula

This lesson will familiarize you with endpoints, how to identify them, and how to find them algebraically. We'll go over what endpoints look like on a graph and what information we need to identify endpoints of a line segment.

### 5. Math Coordinates: Definition & Concept

In this lesson, we will learn about Cartesian math coordinates. Math coordinates give a location on a map or graph. The math coordinates are a way to locate the point on a graph or map, like an address.

### 6. Null Set: Definition & Example

The null set is the set that contains no elements. In this lesson. learn how the null set arises naturally when you place certain restrictions on sets, and explore some very useful properties in set theory.

### 7. Undefined Slope: Definition & Examples

In this lesson, you will learn why the slope of a vertical line is called undefined or infinite. You will also learn about the equation of a line with undefined slope.

### 8. Vertical Line: Equation & Slope

In this lesson, we will study a vertical line and find the equation in which to represent it. We will explore the slope equation and use it to determine the slope of a vertical line.

### 9. What is Slope Intercept Form? - Definition, Equation & Examples

The slope-intercept form is one of several ways you can write the equation of a line. In this lesson, you will learn about the definition and equation of the slope-intercept form and work through some real-world examples.

### 10. Y-Axis: Definition & Overview

The y-axis is the vertical 'ruler' on a Cartesian plane, a two-dimensional graph. Learn why it is important in mathematical graphing and how it relates to describing vertical and horizontal distances.
