Question 203308: 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 (1, 3), (2, 5), (8, 17), (50, 101), and (1000, 2001) all lie on line M.
The points (1, -1), (2, -3), (8, -15), (50, -99), and (1000, -1999) 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.

1. In an equation of a horizontal line, all of the y-values are the same and the x-values can be any value at all.
For example:
or These are both example of horizontal lines, the first passes through y = 5 while the second passes through y = 17.
2. In an equation for a vertical line, all of the x-values are the same and the y-values can be any value at all.
For example:
or These are both equations for vertical lines, the first passes through x = 7 while the second passes through x = 45.
