Answer:
9, the sum of the numbers given in the ratio
Step-by-step explanation:
The reduced ratio 2 : 7 means that two parts correspond to one length and 7 parts correspond to the other length. That is, there are a total of 2+7 = 9 parts in the full length of the segment.
It is convenient to think of the line segment as being divided into 9 equal parts.

<em>Additional comments</em>
It is often helpful to consider the total number of "ratio units" in a given ratio. For example, in this problem, the shorter segment is 2/9 of the whole, and the longer one is 7/9 of the whole.
It can also be useful to consider what a "ratio unit" represents. If the whole segment is 27 inches long, then each of the 9 ratio units will represent 3 inches, for example. This means the division 2:7 is 2(3 in):7(3 in) = 6 in : 21 in.
Answer:
b=12.50p
Step-by-step explanation:
Given :
x y
0 0
2 25
4 50
6 75
8 100
10 125
To Find: Which equation can be used to determine p, the cost of b boots?
Solution :
Using point slope form Find the equation of line of the given coordinates
Let 
Let 
So, formula : 


Now we are given that cost of b boots is p
Since we are given that x axis is Number of Boots and y in price
So in the equation put x = b and y = p
So, equation : b=12.50p
Hence Option 4 is correct
