2. Are these two the same? Defend your claim. y = 7x + 8 10y = 70x + 80 Write down this problem on your COMMUNICATOR Be prepared to share your work with the class. Page 40 of your INB write 2x+3y =2(4x-6) in slope-intercept form

3. ITEMS of BUSINESS Nothing.

4. Have your homework out on your desk.

5. People with 100%, try this honors question: What is the slope and y-intercept of x = 7? Also, graph x = 7

6. Get into your 4-Square Groups write in slope-intercept form Page 40-41 of your INB

7. m b

8. Today’s i-can involves SKILL. What kind of SKILL ? SOLVING EQUATION SKILLZ ?

9. How to solve (for y) like a Write this down on your foldable.

10. Question... What does mean? Easy. It means make fewer things for your eyeballs to look at. Or fewer things for your brain to have to focus on. Example: 1 + 2 + 3 + 4 or 10 Which is easier to look at or to focus on?

11. In math, means... Example: y = 8x – 2x + 10 +x - 12 Add this to your foldable, step 1. and follow along.

12. on your homework problems... COMBINE LIKE TERMS.

13. on your homework problems... COMBINE LIKE TERMS.

14. So is that all there is to ? Well no. There’s more. There’s actually a step that comes before combining like terms.... All you gotta do is ? Add this to your foldable, step 1.

15. Do you recall what it means to ? It means multiply (or divide) everything INSIDE the group by what’s OUTSIDE the group. Example:y = -3(2x – 4)

23. How to solve (for y) like a Write this down on your foldable.

24. WHAT. Is a ? Simple. A COEFFICIENT is a number that is multiplied (or divided) by a variable. Example: 21y or - ½ y

25. Examples: -6y = 18x - 36 or 3y = 9x + 5 Follow along in your foldable.
