  • 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. Shading goes up - or right

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

3. Set of ordered pairs (input and output)

4. Slope of 1/1 - through 0

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

6. No solution

7. Same slopes

8. No fraction or decimal

9. Horizontal line

10. A=b - then b=a

11. Plug in vertices in objective function

12. 1 -2 -3...maybe 0

13. One or more solutions

14. Solid line

15. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

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

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

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

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

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

22. 'Points' from BOTTOM to TOP

23. Vertical line

24. Shading goes down - or left

25. Whats worth

26. Shaded area

27. e.g x

28. A=a it is what it is

29. [2x+3]=9 - [2x+3]=-9 write it both ways

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

31. Soft - parentheses

32. Put is simplest form


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

35. Solve using every equation (use linear combination)

36. Substitute AND simplify

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

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

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

40. 'Points' from side to side

41. Dotted line

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

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

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

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

47. A=b - then ac=bc

48. mx+b=y

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

50. Intersecting points
