Question

Pls help :( I will Fan and medal I'm really desperate : Find the equation of the vertical line containing the point (5,-6)

Answer 1

you want to find the equation of a "VERTICAL" line that contains (5,-6)

If you look at the graph, \(\sf x\ is\ always\ \Large 5\)
therefore, your equation will be simply: \(\Large x=5\)
no matter what y values you have, x should always be 5 to obtain a vertical line.

hope this helps :)
