*I'm answering 4 questions from 9.2 in the homework booklet just so you know. 

7. Graph the ordered pairs in the table of values.

8. Circle the table(s) of values that show a linear relation. Explain your answer. 

A shows a linear relation because "l" goes up by 2, and "m" goes up by 2 starting at 7. 

9. The table of values represents a linear relation.

a. Graph the ordered pairs. 

b. What is the difference in value for consecutive x-values? 

     The value of x increases by 1.

c. What is the difference in value for consecutive d-values?

     The value of d increases by 3.

d. The d-value is 3 times the x-value.

e. Write an expression for d in terms of x. 

      3x

Mariel's Pay it Forward

Part 1: 
What is "Pay it Forward"? To me, "Pay it Forward" is a random act of kindness. It's when you do a good deed for others, and ask for nothing in return.

Part 2: 
My act of kindness is donating gently used clothing to Canadian Diabetes. I chose to do this because I have lots of clothes that I no longer use. A few weeks ago, Canadian Diabetes called and asked if we wanted to donate clothes this year, so I took the opportunity. With my donation, I am just one of the people helping Canadians with diabetes or prediabetes. I collected many unneeded items of clothing from my closet and drawers, and placed them into a garbage bag. I have been planning this act of kindness since December 2nd, but Canadian Diabetes still hasn't picked up my donation.

(My camera hasn't been working lately, but I'll post a picture as soon as my camera works again.)

Part 3:
I think my act of kindness is going to be good. When Canadian Diabetes calls to say they're going to pick up the clothes, I will leave the bag outside my front door, and place a "D" on it to show it's for them. I feel good about what I'm doing because I'm helping a great cause, and making room for new clothes. Since Canadian Diabetes hasn't picked up the clothes yet, I haven't been been able to ask anyone to "Pay it Forward", but as soon as they do, I'll update this post.

Part 4:
I think that the idea of "Pay it Forward" is important because from just one person who decides to show a random act of kindness really inspires other to do so, and that's what counts. I think I made difference because the clothes I've donated goes to Value Village. Some day, the hoodie I donated will be on someone else's back keeping them warm from our cold weather. I know my random act of kindness didn't change the world, but I can start with this, and maybe one day, I could.

Mariel's Proportion Post

Part 1: Definitions & Examples

Ratio: -Part-to-part: Compares different parts of a group to each other.
          -Part-to-Whole: Compares one part of a group.

Rate: -Compares two quantities measured in different units. 

Example:

$6 per 12 cookies or $0.50 per cookie

Proportion: -A relationship that says that two ratios or two rates are equal.

Part 2: Questions...
1. 5 hours to travel 360km is about 72 km/h.

2. Emma saves 28 cents of every dollar that she earns. Emma earned $75 last week. How much money did Emma save last week? Emma saved $21 last week.

Part 3: Equivalent Ratio Statements

Part 4: Proportion Video

Part 5: Social Justice

1.  No. 
2. 

3. It's not fair because in the first case, the person stole 3 BILLION, and only has to go to jail for 40 MONTHS. Yet, the homeless man only stole $100 and has to go to jail for 15 YEARS. 

4. If I were the judge, I'd give the man in the first case a life sentence to jail. And I'd give the homeless man a year sentence to jail plus community service. 

**BONUS QUESTION:

How tall is the tree on the right?

I searched up the average size of a teenage boy and got 167 cm. I measured the boy with my ruler, and he was 2 cm. Then, I measured the tree on the right with my ruler, and it was 6 cm. So if I were to make the size of the boy, and the size of a tree into a fraction, it would be 2/6 or when simplified, 1/3. Then I realized, if I would multiply the average size of a teenage boy by 3, I could get an approximate size of a real tree. If your a bit confused with all my words, here's why I'm trying to say: 

So now we have the answer, we can simplify. The average teenage boy is 1.67 meters, and the tree is approximately 5.01 meters, (I'm sorry if I got the answer wrong, or completely confused you, this is my first time trying to do this kind of proportion question.) 

The tree on the right is approximately 5.01 meters.
