Question

Which scenario is most likely the one shown on the graph?

the total amount of money in the cash register, y, containing $50 in change and small bills and x $100 bills
the total number of puzzle pieces, y, in a brand new 50-piece puzzle, and x brand-new 100-piece puzzles
the total weight of the barbell, y, where the bar weighs 50 pounds and x 100-pound weights are added to it
the total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce

Hi, and welcome to QuestionCove!
Without seeing the graph, it is hard to say definitively what the right answer is. Even so, I can infer from the descriptions what the graph for each scenario *would* look like...
All of the examples given describe Linear graphs
The "Cash" example describes a graph with a y-intercept of 50 and a positive slope of 100.
The "Puzzle" example similarly describes a graph with a y-intercept of 50 and a positive slope of 100.
The "Weights" yet again describe a graph with a y-intercept of 50 and a positive slope of 100.
The "Salad" example--surprise--describes a graph with a y-intercept of 50 and a positive slope of 100.
It seems that having the graph itself might be more important after all, since we would be able to see the "Domain" of the graph (how far to the left and right it goes), to see whether or not it makes sense for each example. For instance, putting 12 100-pound weights on a barbell would be very extreme, but that would actually be a small number of 100-dollar bills to have inside a cash register...

Perhaps you can figure out the answer yourself based on that kind of reasoning; if you'd like more help, I strongly suggest posting or describing the graph you're meant to analyze :)
