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

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

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

5. Hard - brackets

6. No solution

7. Shaded area

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

9. x-value because its value is given

10. A=b - then b=a

11. Whats worth

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

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

14. Set of ordered pairs (input and output)

15. One or more solutions

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

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


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

20. 'Points' from BOTTOM to TOP

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

22. A=a it is what it is

23. Shading goes down - or left

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

25. Same slopes

26. Horizontal line

27. mx+b=y

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

29. No fraction or decimal

30. Put is simplest form

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

32. Dotted line

33. [2x+3]=9 - [2x+3]=-9 write it both ways

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

35. e.g x

36. Intersecting points

37. Substitute AND simplify

38. Vertical line

39. Solve using every equation (use linear combination)

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

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

42. Function whose graph is a line

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

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

45. 'Points' from side to side

46. A=b - then ac=bc

47. Opposite - reciprocal slopes

48. Slope of 1/1 - through 0

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

50. Shading goes up - or right
