4 1/3, 4 1/2, 4 5/6, 5 1/6, 5 2/3, 5 6/6
Answer:
-8 5/12
Step-by-step explanation:
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
So we always make the denominator (bottom number) the same, then when it’s the same we just add!
