a) b) Vectors a = (x 3-2) and b = (3-1 2) are 93.7 degrees apart. Solve for the highest value of x. (15 marks) Use Bresenham's algorithm to draw the line y = 0.5x+1 from (1,1) to (7,4). List the pixel coordinates (x,y) of the six points of the line segment, and show all working. (10 marks) c) Create a way to use Bresenham's algorithm for lines with slope > 1. (4 marks) d) Write pseudo code for a function to draw a regular N-gon. Arguments for the function are location (x,y) and radius r.
