Two triangles a and b have been projected onto a window centered at the origin that is 3 units wide and 2 units high. the projected vertices of a are (0,0),(1.4,1.4),(1.4,0) the projected vertices of b are (0.2,0.9),(0.2,-0.9),(-2,0) find the locations of these vertices after mapping them to a view port whose origin is at the lower-left corner and which is 60 pixel wide by 60 pixels high.
