  • 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. Solve for (3x-4)(x+5)

2. 'Points' from side to side

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

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

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

6. Set of ordered pairs (input and output)

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

8. x-value because its value is given

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

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

11. Horizontal line

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

13. Put is simplest form

14. Shaded area

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

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

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

18. Same slopes

19. Opposite - reciprocal slopes

20. [2x+3]=9 - [2x+3]=-9 write it both ways

21. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

22. Slope of 1/1 - through 0

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

24. Soft - parentheses

25. 'Points' from BOTTOM to TOP

26. Plug in vertices in objective function

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

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

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

30. Hard - brackets

31. One or more solutions

32. Whats worth

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

34. Substitute AND simplify

35. No fraction or decimal

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

37. Solid line

38. mx+b=y

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

40. e.g x

41. Vertical line

42. A=b - then b=a

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

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

45. Solve using every equation (use linear combination)

46. Intersecting points

47. Shading goes up - or right

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

49. Shading goes down - or left

50. Function whose graph is a line
