Answer:

Slope is 25 and the y-intercept is 100. (It will take him 12 weeks)

Explanation:

100 is what you started off with so it counts as the y-intercept. The slope is what slowly increases or decreases over time which is 25. The equation we can make out of this is 400= 25x + 100. Solving this equation, we get 12.
