Washington EOC - Algebra 1: Interpreting Linear Models - Chapter Summary
As you study for the Washington Algebra 1 EOC exit exam, use these lessons to review how to solve problems that may ask you to find the properties of linear models, calculate rates of change or interpret linear relationships. These lessons are conducted by our professional instructors. Watch them to improve your skills in the following:
- Finding the slope and intercept of a line
- Calculating slopes using various forms of linear equations
- Determining the average rate of change of a linear model
- Interpreting rates of change and initial values
- Using data and graphs to interpret linear relationships
- Writing and evaluating linear models
Following these lessons, read the lesson transcripts to reinforce your retention of the information presented in them. Then take the lesson quizzes to discover topics you don't understand, and improve your understanding of these topics using the video tags to return to and study the parts of the lesson that explained them.
1. How to Find and Apply The Slope of a Line
In this lesson, we'll discover all about the slopes of lines. We'll learn about different types of slopes and how to find the slopes of lines. We'll use two methods: the slope formula and the slope-intercept form.
2. How to Find and Apply the Intercepts of a Line
How can you take an equation of a line and find out where it will cross the x- or y-axis? In this lesson, we'll define x-intercepts and y-intercepts and learn how to find them.
3. Calculating the Slope of a Line: Point-Slope Form, Slope-Intercept Form & More
Being able to calculate the slope of a line is a very useful skill to have. Why? Watch this video lesson to find out and learn how to find the slope when working with various equations and various lines.
4. Interpreting the Slope & Intercept of a Linear Model
You've probably seen slope and intercept in algebra. These concepts can also be used to predict and understand information in statistics. Take a look at this lesson!
5. Average Rate of Change: Definition, Formula & Examples
Average rate of change and slope of a line are very interconnected. They are actually one in the same. In this lesson, we will be discovering how they are interconnected.
6. Determine the Initial Value of a Function
In this lesson, you will learn to determine the initial value of a function by studying functions in the form of word problems, graphs and linear equations.
7. Interpret Rate of Change and Initial Value
In this lesson, you'll learn how to interpret the rate of change and initial value of a function. We'll also discuss applying these principles to word problems and in real-world situations.
8. Linear & Direct Relationships
Learn how to tell when you're dealing with linear and direct relationships and what graphs of these relationships should look like. Then, go further and explore how to interpret the slopes of these graphs.
9. Interpreting Linear Relationships Using Data: Practice Problems
Understanding linear relationships is an important part of understanding statistics. This lesson will help you review linear relationships and will go through three practice problems to help you retain your knowledge. When you are finished, test out your knowledge with a short quiz!
10. Writing & Evaluating Real-Life Linear Models: Process & Examples
You make decisions about budgeting and other financial issues using linear models without even realizing it. Learn how to write and evaluate linear models.
