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
help

Hi Sana,sana.noor wrote: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
Are you sure this question has been transcribed properly?
Also, are you sure the answer is C?
What's the source?
Cheers,
Brent

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
