Math 10C

Chapter 7 Linear Equations and Graphs

Lesson 71 Slope-Intercept Form

Focus

The FOCUS section introduces the main concept that will be covered in the lesson.

TEXT Page 340

Read/Work through the  Focus  section at the top of page 340 in  your textbook.

Investigate

Investigate an idea or problem, with a partner if possible.
The investigation provides the background for the ideas presented in the lesson.

Note,  the investigation in the textbook is great, and I encourage you to do it!
But... I suspect that not too many students will have access to all the materials needed, and then... actually follow through and do this.  (but if you do, great!)

You can do the Investigation in the textbook,  or work on the alternate investigation that I provide below.

•	Carefully read through each of the bullet points in this section.

•	If you are unclear about any of these ideas,  ASK YOUR TEACHER FOR HELP!

Check Your Understanding    (Practice Problems)

Doing Practice Problems

Practice problems reinforce the math presented in this lesson.

•	Work through the practice problems for this lesson.
	These problems are for practice, you don’t need to hand them in!
	(your teacher may assign specific questions for you to complete)

•	Use the answers in the back of the book to CHECK YOUR WORK!

•	If you make a mistake, TRY TO FIX IT!

•	If you need help or want more information, view the video solutions provided.

•	If you still need more help,  CONTACT YOUR TEACHER!

Types of Practice Problems

Practice questions require basic understanding of the ideas of the  lesson.

Apply questions will require you to dig deeper for a solution.

Extend questions offer enrichment and extension.

Create Connections questions connect the math to everyday contexts.

Mini Lab (optional)  your teacher may or may not have you do these.

Notes

Question 14,    I spent a bit of time and actually created the diagram
(which I do in the video)
If you want to check out my “finished” work,  here is the link to the result

Question 25,    great question, but, I didn’t do a video for this one.

Video Solution Links

Check your work for every problem you do!
If you make a mistake,  try to fix it!
Use the video solutions for more information.
If a problem still doesn’t make sense, ASK YOUR TEACHER FOR HELP!
