. a. answers vary b. Yes; the taller the person is, the longer his or her reach. c. The independent quantities were represented by the x-axis, while the dependent _quantities were represented using the y-axis. d. A trend line can generalize the trend in the data. 1-18. a. The graph is in the first quadrant because negative lengths do not exist; the range of the data determines the kind of graph. b. Counting by 10’s makes the graph a reasonable size. c. In this situation, including the origin with the graph is not suggested. It is easier to see the trend line when the data are not bunched together, and this can be done by changing the range of the graph to exclude the origin. d. The graph should include the maximum height (that of Yao Ming) on the x-axis and the height of the tunnel on the y-axis. 1-21. a. b. c. d. e. f. g. h. 1-22. a. –8 b. 29 c

Answer:

The answer is y=-x+9.

The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9
