Given that they intersect at a point (5,1) in this case, the other point is important in determining the slope.

If one line always hits the y-axis higher than the other, then that means

1. their slopes are different
2. If the slopes are positive, the slope of the line hitting highest on the y-axis (but below 1) is smaller than the slope of the other line
3. I the slope are negative, the slope of the line hitting lowest on the y-axis (but above 1) will be "larger" than the slope of the other line.

While the absolute values of the slopes switch, the line hitting higher on the y-axis will always have a lower slope, whether +/- or 0.

Lines n and p lie in xy plane. Is slope of line n less than slope of line p?
a. Lines n and p intersect at (5, 1)
b. Y-intercept of line n is greater than y intercept of line p
