We know that Y= mX + b , m=slope, b = y-intercept, also x-intercept is when y=0
===> -2x + b = 0, x=4
So: -2(4) +b=0 => b or y-intercept = 8
Hence: The quantity in Column A is greater.
===> -2x + b = 0, x=4
So: -2(4) +b=0 => b or y-intercept = 8
Hence: The quantity in Column A is greater.

The x coordinate is (4,0) and the Y coordinate is (0,k), the formula for slope is \(\frac{(Y-Y1)}{(X-X1)}\)
\(\frac{(k-0)}{(0-4)}\) = slope = -2
=> k = 8
so, the answer is A
\(\frac{(k-0)}{(0-4)}\) = slope = -2
=> k = 8
so, the answer is A
