So this is our table:
-----------------
x-values | a b c d e f |
-----------------
y-values | g h i j k l |
-----------------
You can know that the values in the table are proportional if:

Hope that helps :)

Step-by-step explanation:

Answer:
42
16
Step-by-step explanation: Well, 1 week = 7 days. So 6 weeks is 6x7 = 42. Because you are looking for the difference between them, you will subtract them. 42 - 2 = 40. And for the 2nd one. 3x7 =21. 21 - 5 = 16.
The correct answer should be A because you have to have a common denominator in order to solve so you take 5/6x and 4/6x and solve.
Answer: The y-intercept should be the $20. The equation would be y=10x+20. Not sure if that’s what you’re asking.
