Some questions will ask you to interpret a given graph, and others will require you to manipulate the objects on the graph or even add new required objects. Each manipulable object will be shown in the area to the right of the graph (the palette) and referred to by its color, object type, and shape of the control points, for example, black point (plus symbol). To place an object on the graph, select it from the palette and drag it onto the graph itself. On the following graph, use the black point (plus symbol) to represent the intersection of the two lines shown. 16 14 Point 12 10 CO PRICE (Dollars per box) 6 A 2 4 8 12 16 20 24 28 32 36 40Getting more information Sometimes, selecting objects on the graphs reveals additional information, such as the coordinates of a point, the slope of a lineg, or the x- and y- intercepts. Be careful when interpreting these values, however, because they do not take into account the units of the axes. For example, you can select the coordinates of the black point (plus symbol) you placed on the graph previously to see that the intersection of the curves occurs at the point representing a quantity of\\:l hoxes. Working with points Once you have placed a point on the graph, you can adjust its position by selecting the point again and repositioning it, or you can drag it off the graph entirely to remove it. Within the graph, the point will automatically snap to certain locations, or snap peints. That is, you may be able to plot only coordinates that occur at multiples of 5 or whole numbers or sometimes even aperiodic intervals such as 1, 2, and 6. On the given graph, it W possible to plot the black point (plus symbol) on the coordinates representing 6 thousand boxes and a price of $12. Working with lines As with individual points, the control points that define a line can be placed only on the snap points of the graph. Often (though not always), snap points coincide with the intersection of grid lines. You are graded on the position of the line itself, not the position of the control points zlong the line. On the following graph, place the green line (triangle symbol) directly on top of the upward-sloping line vou are given. Hint: Make sure you plot the green line at the grid lines. @ Line 1 Line 2 PRICE (Dollars per box) 0+ t t t t t t t t | 0 4 8 12 16 20 24 28 32 36 40 QUANTITY (Thousands of boxes) True or False: The vertical intercept of the line will always be a snap point. O True O False Adjusting lines Once you have placed a line on the graph, you can move the entire object without changing the slope by selecting any part of the line other than the control points, and then dragging it up, down, left, or right to the desired location. To remove the line from the graph entirely, you can select either a control point or the line itself and drag it off the graph. Place the purple line (diamond symbol), labeled Line 2, on top of Line 1. Then, without selecting the control points, shift Line 2 up by $2 at every quantity. Understanding graph grading After you hit the Check Answer button, each palette icon will be marked with either a green check or a red X, indicating whether that object was placed correctly or incorrectly on the graph. In addition to the standard explanations that appear for all questions, a correct version of the graph will also appear next to each graph you constructed. Select this graph (labeled Correct Answer) to swap its position with that of the graph you submitted and to see an enlarged version of it. To switch back to the view with your graded graph being enlarged, select the smaller graph now labeled Your Answer. Note: Not all graphs are graded, some are simply given to you to assist with answering the rest of the question. Unless the instructions tell you that a particular graph is not graded, assume that it will be graded.
