  • 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 to obvious but it re-enforces your understanding as you take the test each time.
1. Second step to linear combo. Fill in variable for whatever you solved for OR change equation to y= or x=

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

3. 'Points' from BOTTOM to TOP

4. [2x+3]=9 - [2x+3]=-9 write it both ways

5. Set of ordered pairs (input and output)

6. Function whose graph is a line

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

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

9. Put is simplest form

10. x-value because its value is given

11. Plug in vertices in objective function

12. Opposite - reciprocal slopes


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

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

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

17. Shading goes down - or left

18. No solution

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

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

21. Shading goes up - or right

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

23. Soft - parentheses

24. e.g x

25. Solve using every equation (use linear combination)

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

27. Intersecting points

28. 'Points' from side to side

29. One or more solutions

30. Vertical line

31. Shaded area

32. Substitute AND simplify

33. 1 -2 -3...maybe 0

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

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

36. A=b - then b=a

37. Slope of 1/1 - through 0

38. A=a it is what it is

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

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

41. Solid line

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

43. Dotted line

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

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

46. Same slopes

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

48. No fraction or decimal

49. Hard - brackets

50. Horizontal line
