GMAT prep coordinate geometry

I am getting "E" whats OA

OA is C. Hmmm...

its best to draw a graph...

statement 1...if the product of x ints are neg, each one indiv. is either negative or positive....you can draw positive and negative sloping lines through 4,3 with both negative and positive x intercepts..

statement 2....one of the y intercepts will be neg, one will be positive..you can draw 2 positive sloping lines through 4,3 or 1 negative sloping line and 1 positive sloping line..inuf

if you take both statements together, there will be one line that will have a positive y and x intercept..this line has to have a negative slope..there is no way to draw a positive sloping line through 2 negative intercepts/positive intercepts...the other line must be positive since it has one negative and one positive intercept

C

Thanks hypik21,
It was poor reading from my part.
I read "product of their slopes negative" as product of slope is "-1" so was looking if the two lines are perpendicular.

Correct, thanks for the explanation!
