Linear equations and slope

by Valentyna Parlak


This lesson will be focus on Slope and Linear Equations. This unit is designed to be used in Algebra I and Algebra II classes and can be modified for intermediate grades. This lesson will have students using various forms of technology such as Internet, Microsoft word, Spreadsheet, and PowerPoint.

During this lesson you will learn how to define and interpret the slope in the slope-intercept form to write equations,recognizing connections between graphs and the real world. You will create Power Point to present the slope problems and post it to this blog ,insert the tables in Microsoft Word, and create one table in Microsoft Excel .

Homework Help

Webmath is a math-help web site that generates answers to specific math questions and problems, as entered by a user, at any particular moment. The math answers are generated and displayed real-time, at the moment a web user types in their math problem and clicks “solve.” In addition to the answers, Webmath also shows the student how to arrive at the answer.

Task

You are to turn in two pages consisting of written text and insert the tables in Microsoft Word, and create one table in Microsoft Excel (it can be any table from the first page of Microsoft Word document), and create four PowerPoint slides to present three relating to the Real Word slope problems. The text in Microsoft Word is to be brief answers given on questions related to the topic “ Linear Equations and Slope”. The tables #1, #2, and #3 are to be 6 rows across and have 5 columns. (Example provided)

                                                 

Microsoft word

1.     Open the Start menu and go to Programs, click on Microsoft word.

4.      Place your cursor on the lines of the columns and row and drag them to desired position.

5.      Than place the cursor in the cell you wish to write text and type. When you are finished, use the Tab key to move to the next cell.

6.      When you finish inserting all the information in your table, highlight the area you wish to change the fonts, size, or color. 

To copy an image found on the Internet.

  • Place your cursor on the image and right click your mouse.
  • Select Save Picture as…(see Image 1)
  • When the save picture menu appears save the image to your network folder. Make sure you rename the image so you can find it later.
  •  Write the file name next to the appropriate term on your work sheet.

To add picture to your PowerPoint slides.

·        On your toolbar go to Insert, Picture, From File….

  • Find your folder where you stored all of the images you copied from the net. Click on the picture that you need.
  • Move the image on the slide by clicking and dragging. Size the image, if necessary, by clocking and dragging the corners.

PowerPoint presentation

                                           

  • Go to the tool bar menu, click on the File and then New…
  • Click on the tab that says Design Templates. Look at the various designs and select one for your presentation. This will be the background for all of your slides.
  • If you have selected a background, the New Slide Menu will appear. Click the Title Slide, which is the upper left icon. (See Image below)
  • On the new slide where it says Click to add title, click there and add a title for your presentation.
  • Click where it says Click to add subtitle and type in your name.
  • To create all of the following slides, you will need to get back to the New Slide menu. Find on your tool bar Common tasks and select New Slide.
  • On the bottom row, select the icon that says Title Only.
  • Click where it says Click to add title and add the name of a term from your assignment.

Your PowerPoint slides must to be readable (slides can be read from a distance). Use at least two pictures or images. Make sure that your grammar, punctuation and spelling is correct.

In Microsoft Excel, students have to create one table, and make sure that all their formulas are correct.

The first row has to have a description of columns and they must to be bold, highlighted, or different font. Example provided.

    Excell

                                                

    To create a table in Microsoft Excel

    1. Open a new spreadsheet file.
    2. Set   up a spreadsheet file that it contain the following information 
    3. Column C and D name as Change in X and Change in Y.
    4. In Cells A2, A3, A4, A5, A6 type the given domain.
    5.  In Cells B2, B3, B4, B5, B6 insert the formula that calculate the Y-value. For example in cell B2 type: = A2 - 4, in cell B3 type =A3 – 4, and so on.
    6.  In cells C3, C4, C5, C6 insert formulas:

         C3: =A3-A2

         C4: =A4-A3

         C5: =A5-A4

         C6: =A6-A5

    9.  In cells D3, D4, D5, D6 insert formulas:

         D3 =B3-B2

          D4 =B4-B3

          D5 =B5-B4

          D6 =B6-B5

                                                                                                         

    Answer the questions:

    A.    Compare the coefficients of x from each equation in Question 2 to the answer in the last row of each table. What do you notice?

    B.     Compare the three tables. How are the results alike? How are they different?

    C.     Graph the three equations from Question 2 on the same set of axes. (Go to website www.gomath.com, click on Auto-Graph, insert your equations, click Get Graph) Describe each graph. Which graph steepest? Which graph least steep?
