  • 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. Put is simplest form

2. A=b - then b=a

3. Intersecting points

4. Shading goes up - or right

5. Substitute AND simplify

6. Hard - brackets

7. Slope of 1/1 - through 0

8. Function whose graph is a line

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

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

11. Vertical line

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

13. 'Points' from side to side

14. mx+b=y

15. No fraction or decimal

16. Shading goes down - or left

17. Whats worth

18. e.g x

19. Dotted line

20. 'Points' from BOTTOM to TOP

21. x-value because its value is given


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

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

25. Solve using every equation (use linear combination)

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

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

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

29. Horizontal line

30. Solid line

31. Same slopes

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

33. Shaded area

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

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

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

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

38. Plug in vertices in objective function

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

40. A=a it is what it is

41. Set of ordered pairs (input and output)

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

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

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

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

46. One or more solutions

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

48. No solution

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

50. Soft - parentheses
