- Finding the Transformed Vectors
Apply the transformation matrix to the following column vector
to find the transformed vector: - Graphing the Transformed Vector
Plot the column vector
on the graph. Then apply the transformation matrix 
to the column vector to find the transformed vector, and plot the transformed vector on the graph. - Plot the column vector

Topic Notes
In this lesson, we will learn how to transform column vectors with matrices. To transform a vector, we need to multiply the transformation matrix with that vector. This would result in a transformed vector, where the length or direction of the vector may be changed. We will take a look at some questions which involve transforming vectors, and then graph them to notice the changes between the normal vector and the transformed vector.
Let be a column vector and be a transformation matrix. Then we can transform the column vector by multiplying it with the transformation matrix . In other words, 
is the transformed vector.
