To answer your questions, let's analyze the information based on the graph description provided:
(a) The cost of buying 1 ounce of cheese: This value can be read directly from the graph. Since 1 ounce corresponds to a specific point on the graph, you can find the y-coordinate for that point to determine the cost in cents.
(b) The cost of buying 1 ounce of cheese: Similar to part (a), this requires locating the point on the graph for 1 ounce and finding the corresponding y-coordinate.
(c) The increase in cost for each additional ounce of cheese: This is typically represented by the slope of the line on the graph. The slope indicates how much the cost increases per ounce of cheese. You can derive the slope by finding the change in cost divided by the change in weight (cost difference per ounce).
(d) To determine whether the amounts given in parts (b) and (c) are equal, consider the relationship between the cost per ounce (part b) and the slope of the line (part c). If the total cost function is linear starting from the origin (0,0), then the cost per ounce (b) will equal the increase in cost per ounce (c).
Now, let's review the answer choices based on this analysis:
-
Yes, because the line passes through 0,0. (This would imply that the cost per ounce and the slope are equal under a linear relationship.)
-
Yes, because the line does not pass through 0,0. (This is incorrect since it suggests a different reasoning.)
-
No, because the line passes through 0,0. (This is incorrect; if the line passes through 0,0, the values could still be equal.)
-
No, because the line does not pass through 0,0. (This could be correct only if the slope was consistent in direction but not equal values.)
In conclusion, without the exact graphical data, we cannot specify numerical answers, but I encourage you to find the specific points to fill in the blanks. However, the best answer for part (d) would likely be "Yes, because the line passes through 0,0." indicating a direct linear relationship, assuming the graph is linear.
