On this page, you will find Algebra worksheets mostly for middle school students on algebra topics such as algebraic expressions, equations and graphing functions. This page starts off with some missing numbers worksheets for younger students. We then get right into algebra by helping students recognize and understand the basic language related to algebra. The rest of the page covers some of the main topics you'll encounter in algebra units.
Introduction Can a cricket be used as a thermometer? In fact yes, crickets vary the number of chirps they produce with the temperature.
If I give you a linear equation to use and a cricket, you can then tell me the temperature.
This is one way you could use an Algebra equation in real life. We will use information from real life situations and we will write linear equations to fit those real life situations.
TheTask We have studied solving and graphing linear equations. We have also studied the slope-intercept form of a line. Now we will visit the Internet and see how linear equations come up in real life.
You will work in groups. Your group will chose a real life situation to investigate. Some of you will compute the number of calories that you will burn dancing or golfing or running. Some of you will investigate car prices, maybe the cost of a TransAm or a Corvette.
You will gather data, write an equation, draw a graph and collaborate to draw conclusions based on analysis of your data.
You will also send e-mail to Dr. All to see how linear equations are part of our daily life. Get into your assigned group. Choose a real life situation from those listed here: Ask your teacher for the worksheet pertaining to the real life situation that your group has chosen to investigate.
Each member of your group will need a copy of the worksheet. Click on one of these linked sites: Each student needs to complete their worksheet using the data acquired from their chosen Internet site.
You will need to complete parts of the worksheet individually and parts of it with the other students in your group. You may certainly ask each other for help as needed. Each group needs to e-mail one question to Dr.
Math about a real life situation. Your question needs to be approved by your teacher before it is mailed. You need to have your teacher's signature by this item on your worksheet. Click on the following site when you have your question ready and approved, scroll down to the e-mail box and send your e-mail.
You'll need to get your school's e-mail address from your teacher. Each student will need to give an oral report in class describing one way they could use this information in their daily life. Your project will be evaluated on the following criteria: Math's site later in the week for his answer to your question.
If you would like to investigate with a cricket in your backyard, here is an equation I found which will approximate that situation: I hope you had fun investigating these real life situations. Many people in many careers write equations and use them to predict situations and to set their sales prices.
Now, you have seen how linear equations are part of your daily life. Teacher Resources A teacher who uses this site will need to print out the worksheets listed below and have multiple copies of these worksheets photocopied.
You will need to either provide the students with graph paper or tell the students to bring their own graph paper. And, you will need to provide the students with your school's e-mail address.©n mK7uEtkaS JSro ZfvtawaaCr5ei rLoLVCA.m K kAzlxlq Qr1iMg8hntqs5 arReNsJe8rFvieRd8.Z G ZMbaZdDeZ uw7ityhw gI7nfxiYnPi9tXeP HArlygkeubwraal leslutinsduphoenix.comheet by Kuta Software LLC Answers to Graphing Linear Equations Using a Table of Values (ID: 1).
• writing and graphing linear functions. Chapter 5 Linear Functions Another way to determine whether a function is linear is to look at its equation.
Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions. Provide additional examples of graphs of linear functions and ask the student to identify the slope and y-intercept and then, write an equation in slope-intercept form. If needed, review function notation and guide the student to use function notation when writing equations of lines. 1oa1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. 1oa2 Solve word problems that call for addition of three whole numbers whose sum is less.
A function is linear if it is described by a linear equation. A linear equation is any equation that can be written in the standard form shown below. A linear equation is the equation of a line, and the graphs of linear equations always display a straight line.
All linear equations must include variables such as x and y and may include a constant or coefficient to a variable but there will be no exponent. Math homework help. Hotmath explains math textbook homework problems with step-by-step math answers for algebra, geometry, and calculus.

The graph is below.
Several of the points are so far from the others that it is not convenient to plot them. This is true of almost all exponential equations.
