Subjects : math, algebra
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. Solid line






2. Function in mx+b=y form whose graph is a line






3. Solve using every equation (use linear combination)

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






5. Shaded area






6. Set of ordered pairs (input and output)






7. Rectangular array of #s written w/brackets (classified by # of numbers in row and column e.g. 3x3)






8. mx+b=y






9. 'Points' from side to side






10. Function whose graph is a line






11. Hard - brackets






12. f(x -y)=x + y






13. One or more solutions






14. Intersecting points






15. Set of all SECOND coordinates of the ordered pairs e.g. y (x -y)(output value - ordinate)






16. Solve for (3x-4)(x+5)






17. Original status a+0=a - ax1=a

23. Whats worth






24. Horizontal line






25. Same slopes






26. Soft - parentheses






27. A=b - then b=a






28. If IxI>5 then x>5 or x<-5






29. A relation in which each element of the domain is paired with one element in the range (no repeated x - however y can repeat)

34. Relations have all points in common e.g same line






35. Vertical line






36. No fraction or decimal






37. Set of all FIRST coordinates of the ordered pairs e.g. x (x -y)(input value - abscissa)






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






39. y-value - because its value depends on the x-value






40. 1 -2 -3...maybe 0






41. A=b - b=c - then a=c
