This problem describes a translation of (x,y) --> (x - 2, y + 4), which describes the amount of units in which the coordinates will shift. To find C', simply perform the equation above by plugging int the values of x and y.
C: [tex](1,1)[/tex]
C': [tex](1 - 2, 1 + 4)[/tex] --> [tex](-1,5)[/tex]
So C' is located at (-1,5).
