What is the slope of line p?

1. x intercept is twice the y intercept
2. The line passes through the I and III quadrant

OA is C

I really cannot understand how the answer is C!

1. says x intercpet is twice of y , so for a line with equation y=mx+c , y intercept = c and x intercept = -c/m

so we have -c/m = 2c and here c's sign does not matter so m=-1/2

2.We dont need this information (??)

so answer according to me should be A

Hi Sana,

Are you sure this question has been transcribed properly?
Also, are you sure the answer is C?
What's the source?

Cheers,

i was solving question from BTG forum and found this question...here is the link

Let's call this an unknown source, since the original question does not site a source.

There are a few problems with this question.
For example, if the x intercept is twice the y intercept, we could say that the line passes through the origin (0,0), in which case the x-intercept (0) is theoretically twice the y-intercept (0).
If the line also passes through the I and III quadrants, then there could be any number of slopes.
So, we could say that the answer is E

Of course, I'm not a big fan of saying that something is "twice" another thing if those two things are both equal to zero. I don't think the test-makers are fond of this either.

My advice is that we skip this question and move along.

Cheers,
Brent
