3. Cars leave a parking lot after a football game.  The table shows the linear relationship between the number of cars remaining in the parking lot and the number of hours after the game ends. ​ Which equation can be used to determine y, the number of cars remaining in the parking lot x hours after the game ended?

• y= -15,000x + 60,000

• y= -15,000x + 45,000

• y= 15,000x + 45,000

• y= 15,000x + 60,000

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

NOTE: 1st Quarterly Exam Question - 24% Correct Overall

• 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 equal to the slope of BD, because the ratios of the rise/run are the same for BC as it is for BD.

• 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 BD.
