There are many benefits to timing your practice, including:

(1) the line could be a straight line with an equation of x = -1 (2) Yes, always goes through Quad 1

TeHCM,
Your argument for #1 can be applied to #2 too. In which case the slope of line is infinity (> 1) and intercept is -1 too _________________

I'm still a bit rusty after all the rest. LOL. Could you elaborate?

Now the line x = -1 (line that parallel to y-axis and passes through (-1,0)), satisfies both condition it's slope is infinity, which is defenitely > 1. Also it has x-intercept of -1. But it doesn't pass through 1st Quadrant.
Hence it should be E. _________________

If line x = -1, shouldn't the slope = 0? _________________

"To dream anything that you want to dream, that is the beauty of the human mind. To do anything that you want to do, that is the strength of the human will. To trust yourself, to test your limits, that is the courage to succeed."

somehow I tend to consider positive, negative, zero and inf four different slopes... and particularly I consider slope of inf is not defined!

in this case I would say B is sufficient, because, any positive slope line is bound to pass through quadrant (I and III) and negative slope will pass through quadrant(II, and IV)

more over any line with positive or negative slope passes through three quadrant!

Ok to clarify my previous stand about slope let me quote bible (OG-11, page 138)

" For vertical line, slope is not defined......"

And if you remember numbers properties 0 is neither positive nor negative itâ€™s just "even evil"

I hope this helpsâ€¦

Hmm.. If OG mentions "slope is not defined" for a vertical line, I would have to take that. In that case B is sufficient. _________________
