(Section 5.5) 0 points 5. a. Find the matrix for a shear in the x-direction that transforms the triangle with vertices (0, 0), (2, 1), and (3, 0) into a right triangle with the right angle at the origin. b. Draw a figure that shows the image of the triangle with vertices (0, 0), (1, 0), and (0.5, 1) under a shear by a factor of 2 in the x-direction
