OpenGL question

Question 2 a) SHOW how 2D Cartesian coordinates (7, 3) can be represented in their equivalent homogeneous coordinates. THEN, apply this as a translation transformation matrix to the line segment [(1, 2), (3,5)], and give the resulting vertices. (3 marks) b) SHOW, using a transformation matrix (homogeneous coordinates), how the line segment [(5, 1), (7,1)] can be scaled by a non-uniform scaling of 4 in the x direction and 3 in the y direction. Provide the scaling matrix and the coordinates of the line segment after this transformation. (3 marks) c) Compute the composite transformation matrix for the translation from (a) followed by the scaling from (b). (4 marks) d) Compute the inverse transformation for the composite transformation you have developed in (c). (4 marks)
