The graph below shows a line of best fit for data relating the number of marbles added in a jar to the total weight of the jar, in grams. The line of best fit used to model the data is y = 4.95x + 160.03. Which statement is true for the above graph?

A.
The y-intercept of the line means that the weight of the empty jar is about 160 grams.
B.
The slope of the line means that, on average, for every 1 gram increase in the weight of the jar, approximately 5 marbles are added to it.
C.
The slope of the line means that, on average, for every 1 marble added to the jar, the weight of the jar increases by approximately 8 grams.
D.
The y-intercept of the line means that, initially, there were about 160 marbles in the jar.
