Question 9
9.

Which of the following is TRUE about the equation?

Question 10
10.

y3
The slope of BC is greater than the slope of BD, because the ratio of the change in y-values to the change in x-values is greater for BC than it is for BD.
The slope of BC is less than the slope of BD, because the ratio of the change in y-values to the change in x-values is less for BC than it is for segment BD.
The slope of BC is EQUAL TO the slope of BD, because the ratio of the change in y-values to the change in x-values is the same for BC as it is for BD .
Question 7
7.

Determine the equation for the graph.
