Coordinate Algebra and Geometry?
I'm not really sure how to work this out, so please help.
How do i find an equation and slope of a line if it gives me x=7? Because the question is 'list 3 points on the line for each given line.' Can you explain the answer to me? And how do i do it if gives me y=(something)?
I also need to find the slope for those 2 above.
Please be simple as possible and thruough. Thank you!

the slope of x=7 is undefined because the line is vertical. you have to find 3 points on the line x=7. some examples are (7,0), (7,5), and (7,7). any point on the line will be (7,n), where n is any number.
the slope of y=something is always zero because the line is horizontal. any point on the line will be (n,y), where n is any number and y is the "something" from y=something.
lets hope this helps. :)
