Chapter 3

USE ANOTHER BROWSER TO SEE ALL OF MY VIDEOS.

See videos in order, or for particular sections in the textbook. The labeling of each video (G1, G2, etc.) is for students in my class. Students need to copy the contents of each video for their Video Notebook if it has a label such as G1.  If there is not label, then it's optional for you view it. You do not include notes for that video in the VN.  Label top of each page with the Video Label given for each video. Students in my Class: For the Video Notebook, label Chapter 3 graphing videos as G1-G24.

THE RED NUMBER STATES THE SECTION.  DO ALL THE VIDEOS LISTED UNDER EACH SECTION.  SO FOR 3.3, DO G7-G8.

I have created several videos in the link Graphing Lines which goes over all 5 sections of Chapter 3.  

3.1 & 3.2: Videos G1-G6 will help you with these 2 sections.

G1: Graphing 1: This video is an introduction to the Rectangular Coordinate System and covers the basic vocabulary, definitions, ordered pairs, and how to plot points on the x-y plane.

G2: Graphing 2: Covers how to determine is a given ordered pair is a solution to an equation and therefore a point on the line.  Also shows how to find ordered pair solutions to a linear equation.

G3: Graphing 3: Covers how to complete ordered pair solutions if the x or y coordinate is given.  Also covers how to make a table of ordered pair solutions if the equation is solved for y, how to plot those on the x-y plane and graph the line.

G4: Graphing 4: Covers how to make a table of ordered pair solutions if the equation is solved for y, how to plot those on the x-y plane and graph the line.  Includes equations with fractions and how to choose convenient values of x in the chart to make computation and graphing points easier.

G5: Graphing 5: Covers how to solve an equation for y so it is easy to plug in convenient values for x, make a table of ordered pairs, plot the points and graph the line.  Also, solving for y will be useful to get equations in slope intercept form and graph using that method, which is covered in later videos.

G6: Graphing 6: Covers the special cases of graphing horizontal and vertical lines which are in the form x=k or y=k, where k is any number.

3.3: Videos 7-8 will help you with this section.

G7: Graphing 7: Covers how to fnd the x and y intercepts of a line, and how to plot those points to graph the line.

http://www.youtube.com/watch?v=S0HoxE0WMXw

G8: Graphing 8: Shows more examples of how to graph lines by making a table or chart of ordered pairs, or using the x and y intercept method.  It also shows how to decide which method is easiest for a given equation.

3.4: Videos 9-17 will help you with this section.

G9: Graphing 9: This covers the concept of slope, what it means and how to find the slope of a line by looking at its graph.

http://www.youtube.com/watch?v=fCIuiQz2Zv4

G10: Graphing 10: This is a continuation of the ideas presented in part 9, and continues to cover the basic idea of slope, what it means, and how you can determine the slope by looking at a graph. More examples are included.

http://www.youtube.com/watch?v=SM3bj7zA0FM

G11: Graphing 11: Covers the algebraic formula used to find the slope of a line passing through two points. More examples are in the next video, Graphing 12.

http://www.youtube.com/watch?v=bploNzF7cxg

G12: Graphing 12: Continuation of the ideas from Graphing 11: More examples showing how to find the slope of a line passing through two points by using the algebraic formula for slope.

http://www.youtube.com/watch?v=hPryexyt6Sg

G13: Graphing 13: Shows how to graph a line if you know the slope and one point on the line.

http://www.youtube.com/watch?v=Ty-ySVSFmEA

G14: Graphing 14: This is an introduction to the slope-intercept form of a line, and how to identify the slope and y-intercept from an equation.

http://www.youtube.com/watch?v=U6x-L49_P0k

G15: Graphing 15: Shows how to graph a line using the slope-intercept method.

http://www.youtube.com/watch?v=XwyMlLpWVS0

G16: Graphing 16: This is a part 2 of Graphing Lines using the slope intercept method.

http://www.youtube.com/watch?v=og4Zo5KiEq8

G17: Graphing 17: This is a summary of the 3 methods for graphing lines.

http://www.youtube.com/watch?v=hs7BxU2strY

See G23 to learn about parallel and perpendicular lines.  That video will help for problems in section 3.4.

3.5: Videos 18-24 will help you with this section.

G18: Graphing 18: This video covers to how to write equations of lines given info about the line.

http://www.youtube.com/watch?v=9h78OnmH6gk

G19: Graphing 19: This video covers how to find the equations of lines if you know the slope and a point.  Goes over the point-slope formula.

http://www.youtube.com/watch?v=kHAZCA7O8UQ
