  • 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. Whats worth

2. Shaded area

3. Shading goes up - or right

4. A=b - then b=a

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

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

7. Plug in vertices in objective function

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

9. Dotted line

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

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

12. 'Points' from side to side

13. 1 -2 -3...maybe 0

14. Same slopes

15. Slope of 1/1 - through 0

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

17. 'Points' from BOTTOM to TOP

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

19. x-value because its value is given

20. Substitute AND simplify

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

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

23. Soft - parentheses

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

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

26. Change of grouping a+(b+c)=(a+b)+c

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

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

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

30. Intersecting points

31. mx+b=y

32. Function whose graph is a line

33. One or more solutions


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

36. Vertical line

37. Put is simplest form

38. A=a it is what it is

39. Horizontal line

40. No solution

41. Solve using every equation (use linear combination)

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

43. A=b - then ac=bc

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

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

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

47. Set of ordered pairs (input and output)

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

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

50. Opposite - reciprocal slopes
