Quantitative Comparison..(please solve it)

[umerilyas]

In the xy-plane, line "L" has slope 1.

Col A: The value of x-intercept
Col B: The value of y-intercept


[[[[[[[in figure, there is a inclined line(towards right side), intercepting y-axis(positive side) and intercepting x-axis(negative side) ]]]]]]]
no coordinate given.

It is a powerprep quantitative comparison.in practice section...
I know the answer...but please anyone explain it to me....

sitting for GRE tomorrow...
Thanks!!!!!!!

slope one mean angle is 45 or pi/4 .. (y2 - y1)/(x2 - x1) = tan (pi/4) = 1
y1 = 0; x2 = 0
let y 2= a (intercept on y axis)
nd x 1 = b (intercept on x axis)
a/(-b)= 1
b = -a

thts it ..

and da answer is d.. if a = 0, b = 0. if a = -1 b=1.. if b=-1, a = 1.
