From the given set of data:
 60, 58, 53, 49, 60
the mean is 56
the variance will be found using the formula:
variance=[Σ(x-μ)²]/N
[Σ(x-μ)²]=(60-56)²+(58-56)²+(53-56)²+(49-56)²+(60-56)²
            =16+4+9+49+16
            =94
but N=5
thus
Variance=94/5=18.8

If you graph all of the lines that are listed, the only line that will reflect ABCD onto itself is x + y = 4.

Step-by-step explanation:

hope this helps you :)
