PLEASE HELP WILL GIVE BRAINLIEST PLEASE PLEASE PLEASE ASAP!!
The chart below summarizes the results of a 5th grade experiment comparing student height to student arm span. Which of the following equations would be a suitable equation for a line of best fit for the data in the chart?

Height (in.)

42
45
52
48
49
53
59
45
44
60

Arm span (in.)
41
43
55
49
49
52
60
44
45
67

A.
y=-x+7
B.
y=-x
C.
y=x
D.
y=x+7

Respuesta :

I think the answer is C because there isn't really a pattern, it's increasing then decreasing then increasing and decreasing and so on. So if you do find a pattern then it wouldn't be C for sure, but since there is no pattern I'm going for C.
Hope that's right. .-.

Answer:

Option: C is the correct answer.

             C.   y=x

Step-by-step explanation:

We are given a set of data values as:

       Height(in.)       Arm span(in.)

           42                        41

           45                        43

           52                        55

           48                        49

           49                        49

           53                        52

           59                       60  

           45                        44

           44                        45    

           60                       67

on plotting these points we see that the line that best represent these data points is a linear graph and the equation of the line of best fit is:

                                y=x
