  • 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. f(x -y)=x + y

2. Whats worth

3. No fraction or decimal

4. # set (2 -3) in x+1=y - 2+1=3

5. Change of order a+b+c=a+c+b

6. Solve using every equation (use linear combination)

7. One or more solutions

8. Slope of 1/1 - through 0

9. Correct result - but doesn't work in equation

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

11. A=b - then ac=bc

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

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

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

15. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

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

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

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

20. Set of ordered pairs (input and output)

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

22. No solution

23. Relations do not have all points in common e.g diff. lines that may intersect

24. mx+b=y

25. Opposite - reciprocal slopes

26. Ax+By=C (letters are real - not zero)

27. x-value because its value is given

28. Shading goes down - or left

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)


31. Function whose graph is a line

32. Intersecting points

33. Soft - parentheses

34. Plug in vertices in objective function

35. 1 -2 -3...maybe 0

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

37. Dotted line

38. Solid line

39. Vertical line

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

41. Put is simplest form

42. Shaded area

43. [2x+3]=9 - [2x+3]=-9 write it both ways

44. Same slopes

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

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

47. 'Points' from side to side

48. Shading goes up - or right

49. 'Points' from BOTTOM to TOP

50. e.g x
