6. (10 pts) If point A has coordinates (x,y) of (30, 100) and point B has coordinates of (120, 300) what is the direction of line AB? State as an azimuth and as a bearing. 7. (10 pts) Line A has the equation of 2x + 4y +16= 0 and line B has the equation of 4x-2y + 24 = 0. What are the coordinates of the intersection of these two lines at point P? 8. (10 pts) Points A and B define a line and points C and D define another line. Coordinates (x,y) for the points are: A = 15, 10 B = 49, 25 C = 28,7 D = 32, 32 What are the coordinates for the intersection of the two lines? Use the trig method to solve. 9. (10 pts) Determine the points of intersection of the line with an equation of 2x +2y = -1 and the circle with the equation (x-2)² + (y+3)² = 4.
