Homework Statement
Write down the 2 × 2 matrix that represents the following linear transformation of
the plane. Also draw the image of the (first quadrant) unit square 1.
T(x, y) = (2x +6y, x + 3y).
Homework Equations
T(x, y) = (2x +6y, x + 3y).
The Attempt at a Solution
So the previous four questions were as follows:
(a) A dilation with horizontal dilation factor 2 and vertical dilation factor 1/2.
(b) A vertical shear with factor −1/2.
(c) A rotation of 45◦ anticlockwise.
(d) A reflection across the line at angle −30◦ to the X-axis.
I've done all of these without a problem, but I'm not exactly sure what method you use to actually figure out this one? What exactly is the transformation that's happening? I'm stuck as to what the equation actually means, and I should be okay from there.
