Triangle ABC and triangle EBD are similar right triangles. The coordinates of all vertices are integers.


Which statement is TRUE about the slope of BC and the slope of BD ?
The relationship between the slope of BC and the slope of BD cannot be determined because the triangles are overlapping.
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 .
Consider the graph shown. Determine the equation of the graph.


Consider the following table.


If the number of Bull's-Eyes Made represents x, and the Points Displayed represents y, which statement is TRUE?
The following table displays a non-proportional relationship.
The following table displays a proportional relationship.
