Homework Help: More on linear transformations

  1. Nov 18, 2005 #1
    i think i'm just having a hard understanding linear transformations...

    i was asked if (5, 0) is a vector in R(T) given by the formula
    T(x,y)=(2x-y,-8x + 4y)...i really don't get what i'm supposed to do here.. any hints would be most appreciated.

    It asks if the vector (5,0) is in the range of the function T.
    So does there exist some vector (x,y), such that T(x,y)=(5,0)?

    How would you go about this problem?
