Answer: C) center C and scale factor 2
Step-by-step explanation:
Since, The center of a dilation is a fixed point in the plane about which all points are expanded or contracted.
Therefore, By the given diagram we can say that the image is dilated along the point C.
⇒ C is the center of the dilation.
Since, for the given diagram the scale factor of dilation = =
Thus, the scale factor is 2.
Therefore, Option C is correct.

First we are going to express both equation in terms of 
to compare their slopes:
For our first equation:
For our second equation:
So now we have our system of equations in terms of y:
Notice that the slope, the coefficient of
, in both equations is the same: 1, and if tow linear equations have the same slope, they are parallel.
We can conclude that we can classify the system of equations as parallel.
