Exam 22:Understanding Graphs

Exhibit 1-8 -Suppose a graph with Ron's weight on the vertical axis and his consumption of ice cream on the horizontal axis indicated that for each serving of ice cream he ate, Ron would gain 3 pounds, regardless of how much ice cream he had already eaten. This graph would show a

On a graph, the origin represents

Exhibit 1-2 -In Exhibit 1-2, at x = 12, the

The slope of a steep upward-sloping line is a smaller value than the slope of a nearly flat upward-sloping line.

Exhibit 1-4 -Which of the following must be true of line D in Exhibit 1-4?

If slope = 2 for a line on a graph with x on the horizontal axis and y on the vertical axis, then if

One economic application of the slope of a line is

The statement that there is an inverse relationship between x and y means that

Exhibit 1-6 -The slope of a line is defined as the

Exhibit 1-16 -Refer to exhibit 1-16. Which of the graphs illustrates a direct or positive relationship between variable X and variable Y?

If a given value of x is associated with a particular value of y,

Exhibit 1-7 -The slope of the straight line in Exhibit 1-5 is
