Answer:
4. C)
3. B) 9,6 = the number of points you would increase each hour of studying; 65,8 = your score if you studied 0 hours
2. B) The events have a strong positive linear correlation.
1. C) Find the slope using the slope formula:
Step-by-step explanation:
4. (−7, 10) → 10 = 7 + 3 ☑
(−1, 4) → 4 = 1 + 3 ☑
(0, 3) → 3 = 0 + 3 ☑
(3, −2) → −2 ≠ −3 + 3; 0 ☒
3. You obviously have to plug "0" in for <em>x</em><em> </em>to get your initial value of 65,8, which represents the minimum value of points you would receive if you never were to study, and of course, the 9,6 is the average score increased for every hour studied.
2. The correlation coefficient is 0,02, which is positive, so this would be the obvious choice.
1. You CANNOT write a linear equation without FIRST finding the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]. You will ALWAYS need the rate of change in order to write any linear equation.

You need to add all those numbers together and there your answer !! Good luck !
<span>6(x + y) + (x - y)
Use distributive property
(6x + 6y) + (x - y)
Combine like terms (Add x to 6x while subtracting y from 6y)
Final Answer: 7x + 5y</span>
At the end of the third day, the new reading on the odometer will be 12,578 mi
<h3>
What will the odometer reading at the end of the third day?</h3>
The initial odometer reading is 12,386 miles.
Then, the driver takes drives to and from work, such that each trip is 32 miles. Then each day he drives 2*2mi = 64 miles.
And he does this for 3 days, then the total distance driven is:
3*64mi = 192 miles.
At the end of the third day, the new reading on the odometer will be:
R = 12,386 mi + 192mi = 12,578 mi
