Instructions:
  • 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. Put is simplest form






2. A=b - then b=a






3. Intersecting points






4. Shading goes up - or right

8. Function whose graph is a line






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






10. Change one equation with LCM (i think) and add up - cancelling one variable out

15. No fraction or decimal






16. Shading goes down - or left






17. Whats worth






18. e.g x






19. Dotted line






20. 'Points' from BOTTOM to TOP






21. x-value because its value is given






22. ROW x COLUMN

49. Undoes operation a+(-a)=0






50. Soft - parentheses
