Which of the following graphic forms uses axes for data representation?

The correct answer is that both the line graph and bar graph use axes for data representation. In these types of graphs, the horizontal axis (x-axis) and vertical axis (y-axis) are clearly defined, allowing viewers to interpret and analyze the data effectively.

A line graph displays data points connected by line segments, which makes it easy to observe trends over a period. It typically uses the x-axis for the independent variable (such as time) and the y-axis for the dependent variable (such as temperature or sales figures).

Similarly, a bar graph represents categorical data with rectangular bars, where the lengths of the bars correspond to the values they represent. The x-axis often lists the categories, while the y-axis indicates the values associated with those categories, enabling quick comparisons between different data sets.

In contrast, a pie chart, which is designed to show proportions of a whole, does not utilize axes. Instead, it represents data in a circular graph format where each slice corresponds to a category's relative size within the total. Thus, the use of axes is a defining feature of line and bar graphs, while pie charts utilize angles and areas without the need for axes.
