  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 'Points' from BOTTOM to TOP

2. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

3. y-y{2}=m(x-x{2})

4. Put is simplest form

5. Opposite - reciprocal slopes
