Subjects : math, algebra
  • 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. mx+b=y

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

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

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

5. x-value because its value is given

6. Whats worth

7. Opposite - reciprocal slopes

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

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

10. Set of ordered pairs (input and output)

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

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

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

14. Hard - brackets

15. Shading goes down - or left

16. Substitute AND simplify

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

18. Put is simplest form

19. No solution

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

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

22. e.g x

23. 'Points' from BOTTOM to TOP

24. A=a it is what it is

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

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

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

28. 1 -2 -3...maybe 0

29. Solve using every equation (use linear combination)

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

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

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

33. Dotted line

34. Horizontal line

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

36. A=b - then b=a


38. Same slopes

39. Plug in vertices in objective function

40. Slope of 1/1 - through 0

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

42. Shaded area

43. Shading goes up - or right

44. A=b - then ac=bc

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

46. Solid line

47. Intersecting points

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

49. One or more solutions

50. No fraction or decimal
