7. Connected points and curves

Common features among graph objects

Each object you can manipulate or place on the graph has its own unique features as well as some features that are shared with other graph objects. A common feature is that each of these items, when required, will be represented on the palette. As long as a particular palette symbol remains in color, you may drag additional instances of that object onto the graph. Note that sometimes you will be given more instances of a particular object than you are required to place on the graph, so just because the palette remains in color does not mean you must place additional items on the graph.

Drag as many orange points (square symbol) from the palette as you can onto the graph.

Working with connected points

When using the connected points tool, it is important to plot the points in the correct order or else your work will be scored incorrectly. Once you have placed points on the graph, you can change the shape of the object by selecting and dragging any one of the points.

Use the orange points (square symbol), labeled Connected Points 1, to connect the points with coordinates (1,4), (3,6), (5,4), going from left to right. Then use the blue points (circle symbol), labeled Connected Points 2, to plot those same coordinates in the following order: (1,4), (5,4), (3,6).

1.If two connected points objects pass through the same set of three points, the shapes created by each may be different, depending on the order in which each object was plotted.

True

False

Working with curves

Each curve that you place on the graph will have at least three control points connected by a curved line. Rather than dragging each point onto the graph from the palette individually (as with connected points), you must drag the entire object onto the graph as a single unit. You can then change the shape by selecting and dragging one of the control points, or you can move the entire curve as a whole and retain its shape by selecting any point on the curve between the control points and moving the intact curve around the graph. As with connected points, it is important to plot the points in the proper order.

Use the purple curve (diamond symbols), labeled Curve 1, to connect the points shown on the graph so that the curve passes through the points in the following order: (1,4), (3,6), (5,4). Then use the green curve (triangle symbols), labeled Curve 2, to connect those same points, this time passing through the points in the following order: (1,4), (5,4), (3,6).

Explanation / Answer

Your score depends on the order in which you plot the points: This applies for none .

The second adjusting of points is true for : connected points.

Selecting points reveals the coordinates in : Curves

If you plot one point incorrectly and other correctly you may receive partial credit : This applies to none.
