The red crosses belong to a specific 'x'.[br][br]Type in two calculations to move the red crosses to the green dots.
Develop and describe a technique.[br][br]The next three applets generate questions. Practice until you have a reliable technique. [br][br]The first shows increasing functions, the second: decreasing and the last: a mixture.
Describe your technique in task 5.
What if anything, is different about calculating the coefficients for a decreasing linear function?
Explain your technique for calculating the linear relation from the table and/or graph. In your explaination, refer to the 'x' coordinate and the 'y' coordinate.
