For any linear transformation T between \(R^n\) and \(R^m\), for some \(m\) and \(n\), you can find a matrix which implements the mapping. This means that multiplying a vector in the domain of T by A will give the same result as applying the rule for T directly to the entries of the vector. Linear Transformations on the Plane A linear transformation on the plane is a function of the form T(x,y) = (ax + by, cx + dy) where a,b,c and d are real numbers. If we start with a figure in the xy-plane, then we can apply the function T to get a transformed figure. When a transformation maps vectors from \(R^n\) to \(R^m\) for some n and m (like the one above, for instance), then we have other methods that we can apply to show that it is linear. For example, we can show that T is a matrix transformation, since every matrix transformation is a linear transformation .
