Which of the following are considered pictorial models?

Pictorial models are visual representations that help convey information or illustrate concepts. In this context, both graphs and drawings serve as effective pictorial models. Graphs can visually depict relationships between variables, making complex numerical data more accessible and easier to understand. They typically use points, lines, or bars to illustrate changes and trends.

Drawings are also considered pictorial models as they can represent objects, scenarios, or concepts in a visual format. They can make abstract ideas more concrete and relatable, thereby enhancing comprehension.

While tables provide organized data, they do not present that information visually in the same way as graphs and drawings. Thus, selecting both graphs and drawings as the correct answer reflects an understanding of how these tools represent information pictorially, distinguishing them from purely numerical or textual formats like tables.
