2. How do we write the equation of a vertical line? What would be an example?
3. The points (3,9), (5,13), (15,33), (34,71), (678, 1359), and 1234,2471) all lie on M. The points (3,-9), (5,-11), (15,-21), (43,-40), (678, -684), and (1234, -1240) all lie on line N.
a. Form the equations of both the lines. Show your work.
b. What are the co-ordinates of the point of intersection of lines M and N?
c. Write the co-ordinates of the intersections of lines M and N with the x-axis.
