  • 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. Intersecting points

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

3. x-value because its value is given

4. Shading goes up - or right

5. Set of ordered pairs (input and output)

6. 'Points' from BOTTOM to TOP

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

8. Substitute AND simplify

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

10. A=b - then b=a

11. [2x+3]=9 - [2x+3]=-9 write it both ways

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

13. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

14. Solid line

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

16. Horizontal line

17. Solve using every equation (use linear combination)

18. Same slopes

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

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

21. Whats worth

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

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

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

25. Plug in vertices in objective function

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

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

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

29. Shaded area

30. Soft - parentheses

31. Vertical line

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

33. No fraction or decimal

38. Function whose graph is a line

39. Shading goes down - or left

40. No solution

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

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

43. Put is simplest form

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

45. mx+b=y

46. A=b - then ac=bc

47. One or more solutions

48. e.g x

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

50. Opposite - reciprocal slopes
