SOLUTION: Write equations for the vertical and the horizontal lines passing through the point (8,6) in (X.Y) -coordinates. vertical line: horizontal line:

Question 222913: Write equations for the vertical and the horizontal lines passing through the point (8,6) in (X.Y) -coordinates.
vertical line:
horizontal line:
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
A horizontal line is always in the form y= a number.
A vertical line is always in the form x= a number.

Therefore, in this case, with lines passing through (8,6), the horizontal line is y=6, and the vertical line is x=8.

For additional explanation on this type of problem, please see my own website. Do a "Bing" search for my last name "Rapalje". Look for "Rapalje Homepage" near the top of the search list. On my Homepage near the top, look for the link "Basic, Intermediate and College Algebra: One Step at a Time." Choose "Basic Algebra", and look in Chapter 4 GRAPHING and SLOPE of a Line. In these sections, you will find my own non-traditional explanations, that my own students all said were a LOT easier to understand than traditional textbooks. See also the corresponding "MATH IN LIVING COLOR" pages in which problems are solved IN COLOR! I also have FREE videos on the website of me teaching my classes a few years ago. To access the videos, go back to my Homepage, and look for the link "Rapalje Videos in Living Color." Select "Basic Algebra", and select the video on "Graphing and Slope of a Line."
