The question asks per week. So 1.5 cups times 7 days is 10.5 cups.
The pipe leaks 10.5 cups every week.

A point doesn't have slope. Once you have TWO points, then the line between them has a slope.
The slope is (how far the line rises from one point to the other) divided by (the level distance between them).
