  • 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. A=a it is what it is

2. No fraction or decimal

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

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

5. Soft - parentheses

6. Put is simplest form

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

8. mx+b=y

9. Shading goes down - or left

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

11. 'Points' from side to side

12. Set of ordered pairs (input and output)

13. Shaded area

14. Vertical line

15. 1 -2 -3...maybe 0

16. Intersecting points

17. Horizontal line

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

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

20. 'Points' from BOTTOM to TOP

21. No solution

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

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

24. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

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

27. Opposite - reciprocal slopes

28. e.g x

29. Dotted line

30. Whats worth

31. Solid line

32. One or more solutions

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

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

35. Substitute AND simplify

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

37. x-value because its value is given

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

39. Solve using every equation (use linear combination)

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

41. Function whose graph is a line

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

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

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

45. Slope of 1/1 - through 0

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

47. Hard - brackets

48. A=b - then b=a

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

50. Same slopes
