Question 74297: Hey,
im the girl from before with the question about equations & such.
i still don't get it.
I put that answer in & it said it was wrong.
im not sure how to do this.
It gives me graphs to work it out on, but I still don't know how.
Please can you explain it too me once more.
Im sorry to keep bothering you, i just really want to understand this.
It says,
What is the equation of the vertical line that passes through the point (-1,-3)
THANKS!
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Any vertical line will have the equation in the form x=k where k can be any number. In this case, we don't care about y. If we say x=1, then we will have a line through (1,0) (1,1) (1,2) etc. In other words, it will pass through every point with the x-coordinate of 1. So if a point passes through (-1,-3) then the equation is x=-1 which will pass through every point with a x-coordinate of -1.
