  • 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. Shading goes up - or right

3. Substitute AND simplify

4. Horizontal line

5. A=a it is what it is

6. Set of ordered pairs (input and output)

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

8. No solution

9. 'Points' from BOTTOM to TOP

10. Shaded area

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

12. Plug in vertices in objective function

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

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

15. mx+b=y

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

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

18. Vertical line

19. Opposite - reciprocal slopes

20. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

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

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

24. Same slopes

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

26. Dotted line

27. Put is simplest form

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

29. One or more solutions

30. Solid line

31. Function whose graph is a line

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

33. Soft - parentheses

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

35. No fraction or decimal

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

37. A=b - then b=a

38. Slope of 1/1 - through 0

39. 'Points' from side to side

40. 1 -2 -3...maybe 0

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


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

44. A=b - then ac=bc

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

46. Solve using every equation (use linear combination)

47. e.g x

48. Hard - brackets

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

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