It's a linear function: y = mx + b
We have (138; 112.96); (209; 142.78)
substitute the values of x and y to the formula of slope m:

Now we have: 
We must find b. Substitute the value of x and y from first pair of numbers:

Answer: y = 0.42x + 55
Answer:
6
Step-by-step explanation:
Given I varies inversely with R then the equation relating them is
I =
← k is the constant of variation
To find k use the condition R = 12 when I = 3
k = IR = 3 × 12 = 36
I =
← equation of variation
When I = 6, then
6 =
, hence
R =
= 6
Answer:
I think Courtney's will. My reason is because, she travels the fastest ever minuet. She will get there first, because she travels 5.5 every minute, while the others travel 4, and 3.5 per minute.
