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
It’d be B, -2
You move right one space and then down two spaces
