ok we are supposed to go to

Find 3 different matrices that reflect the following transformations,

1. Rotation by $\dfrac{\pi}{4}$

2. Shear along $x$ by a factor of $k$

3. Reflection by the line $\theta$

there are some more but the site asked for doesn't return the transformed matrix just a morphed image

also I presume we doing all 3 matrices with just the matrix's used in the site

I tried geogebra and W|A also but the plots didn't look like vectors

anyway this is due on Friday so hope I can get it right. Im sure the answer is relatively simple
