  • 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. Solid line

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

3. Plug in vertices in objective function

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

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

6. Opposite - reciprocal slopes

7. Soft - parentheses

8. One or more solutions

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

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

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

12. 'Points' from side to side

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

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

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

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

17. Horizontal line

18. Substitute AND simplify

19. Whats worth

20. Hard - brackets

21. A=a it is what it is

22. Shading goes up - or right

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

24. 'Points' from BOTTOM to TOP

25. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

26. A=b - then ac=bc

27. e.g x

28. Same slopes

29. x-value because its value is given

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

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

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

33. Solve using every equation (use linear combination)

34. Shading goes down - or left

35. No solution

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

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

38. [2x+3]=9 - [2x+3]=-9 write it both ways

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

40. Put is simplest form

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

42. Function whose graph is a line

43. mx+b=y

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

45. Intersecting points

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

47. 1 -2 -3...maybe 0

48. A=b - then b=a

49. Set of ordered pairs (input and output)

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