# Equations of lines

Please help me with these problems and please show all work and steps to your solutions. This will help me better understand the problems once I have the answer and the steps for it. Thanks!

Please show work

1. How do we write the equation of a horizontal line? What would be an example?

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 line M.

The points (3, -9), (5, -11), (15, -21), (34, -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.

d. Write the co-ordinates of the intersection of lines M and N with the y-axis.
