Question in Demos
Find a regression equation.
Now includes a graph of the regression line and another interactive graph gives users the opportunity to move the regression line around. Could be used for allowing users to experiment with what they think the line should be and see how this compares with the calculated line.
Also includes an updated SSE to see how the sum of the squares of the residuals varies with the regression line.

Question in Functions and Graphs
This task is part of a set of three assessment tasks for 7.RP.2.
7.RP.2 Robot Races asks students to "explain what a point (x,y) on the graph of a proportional relationship means in terms of the situation" and to "compute unit rates associated with ratios of fractions." Students also need to compare the speeds of the robots.

Question in Graeme's workspace
This question plots a general amplitude modulated carrier signal defined by vs(t)=(VDC+Vmcos(2πfmt))cos(2πfct), where VDC is a DC offset, Vm is the message amplitude, fm is the message frequency and fc is the carrier frequency (fc=20fm in this question). The student must identify the values of VDC and Vm and enter these values into the appropriate gaps in the equation of the AM signal.
