Answer 1

I can’t see the picture — could you upload it or tell me the coordinates/points shown on the graph (for example two plotted points like (10 pennies, 305 g) and (20 pennies, 330 g))?

How to get the jar mass from that graph (so you can check quickly):
1. Pick two clear points on the line: (p1, m1) and (p2, m2) where p = number of pennies and m = mass in grams.
2. Compute the slope (mass per penny): slope = (m2 − m1) / (p2 − p1).
3. Use point–slope or solve m = slope·p + b for b (set p = 0 to find b). b is the mass of the jar (the y‑intercept).

If you give me two points from the graph I’ll compute it and pick the correct choice.
