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

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

3. Dotted line

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

5. [2x+3]=9 - [2x+3]=-9 write it both ways

6. Horizontal line

7. mx+b=y

8. x-value because its value is given

9. Plug in vertices in objective function


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

12. Soft - parentheses

13. Same slopes

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

15. Shading goes down - or left

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

17. Second step to linear combo. Fill in variable for whatever you solved for OR change equation to y= or x=

18. 'Points' from BOTTOM to TOP

19. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

21. Hard - brackets

22. Shaded area

23. e.g x

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

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

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

27. A=b - then ac=bc

28. Intersecting points

29. Set of ordered pairs (input and output)

30. Solve using every equation (use linear combination)

31. No solution

32. Solid line

33. Vertical line

34. 1 -2 -3...maybe 0

35. Set might require positive integers - natural #s - positive reals - etc.

36. A=a it is what it is

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

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

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

40. Slope of 1/1 - through 0

41. Opposite - reciprocal slopes

42. Substitute AND simplify

43. Put is simplest form

44. One or more solutions

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

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

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

48. No fraction or decimal

49. Shading goes up - or right

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