Suppose the number of households (in millions) that have at least one television set can be estimated by the equation y=0.6x + 83, where x is the number of years after 1999.
a. Use this equation or a graph of it to complete the ordered pair (6).
b. Write a sentence explaining the meaning of the answer found in part (a).
c. If this trend continues, how many households will have at least one television set in 2011?

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
