1. Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.
3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4. Test the residuals of two other points to determine how well the line of best fit models the data.
I've included a picture of my graph down below I just really need number 1 and 2 at the moment but any question answered through 1 and 4 would we very appreciated :) thank you very much :D I will be reporting answers that aren't correct, silly, or unhelpful because I just really need these answers and it only allows up to 2 people to answer.

I suck at math so be nice n help:)
Answer: See explanation
Step-by-step explanation:
1. ∠WOV and m∠30° are complementary angles so they should add up to 90°
∠WOV + 30 = 90
Subtract 30 from both sides
∠WOV = 60°
I used the relationship of complementary angles.
2. ∠YOZ and ∠WOV are vertical angles so they're congruent.
∠YOZ ≅ ∠WOV
∠YOZ ≅ 60°
∠YOZ = 60°
I used the relationship of vertical angles.
I hope this helped!

5. How many miles can a car travel on 15 gallons of gas if it travels 28 miles on 1 gallon of gas?
A. 43 miles
B. 270 miles
C. 405 miles
D. 420 miles
My answers:
1. D. 72inches-2 yards
Reason: I kinda guessed on this one
2. D. 423 mph
Reason: 3/1,269, 3 doesn't go into 1 so change that to does 3 go into 12? Yes, 4 times because 4 * 3 is 12 so put the 4 on top of the 2 and times 4 * 3 which again is 12 so 12 - 12 = 0 so then bring the 69 now and 3 goes into 69, 23 times so the answers is 423 I believe.
3. D. Bag A and Bag B are equally good values
Reason: I uh guessed on this one too because I don't have a clue what the answer is
4. C. 320 words
Reason: I timesed 40 by 8, 8 times 0 is 0, 8 times 4 is 32 put the so the answer is 320 I hope
5. D. 420 miles
Reason: 28 times 15, 8 times 5 is 40 so put the 0 under the 5 and put the 4 over the 2, 5 times 2 +4 is 14 so the first number is 140. put a 0 under the first 0 because we don't use that spot anymore, 1 times 8 is 8 and 1 times 2 is 2 so the second number is 280, 280 + 140 = 420. 0 + 0 = 0, 8 + 4 = 12, add the one to the hundered place so 2 + 1 + 1 = 4.
