  • 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. Opposite - reciprocal slopes

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

3. No fraction or decimal

4. e.g x

5. Plug in vertices in objective function

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

7. Put is simplest form

8. Solid line

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

10. Shading goes up - or right

11. Vertical line


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

14. Soft - parentheses

15. Shaded area

16. A=b - then b=a

17. Same slopes

18. Dotted line

19. A=a it is what it is

20. A=b - then ac=bc

21. 'Points' from side to side

22. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

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

25. Hard - brackets

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

27. Set of ordered pairs (input and output)

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

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

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

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

32. Intersecting points

33. Function whose graph is a line

34. Horizontal line

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

36. One or more solutions

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

38. 'Points' from BOTTOM to TOP

39. x-value because its value is given

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

41. [2x+3]=9 - [2x+3]=-9 write it both ways

42. Whats worth

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

44. mx+b=y

45. No solution

46. Solve using every equation (use linear combination)

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

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

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

50. Slope of 1/1 - through 0
