  • 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. Shading goes up - or right

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

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

5. One or more solutions

6. Vertical line

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

8. Put is simplest form

9. Plug in vertices in objective function

10. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

12. Shading goes down - or left

13. A=b - then ac=bc

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

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

16. Solve using every equation (use linear combination)

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

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

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

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

21. Soft - parentheses

22. Whats worth

23. e.g x

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

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

26. Opposite - reciprocal slopes

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

28. Slope of 1/1 - through 0

29. Substitute AND simplify

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

31. Dotted line

32. mx+b=y

33. Intersecting points

34. Shaded area

35. Function whose graph is a line

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

37. Same slopes

38. 'Points' from BOTTOM to TOP

39. Set of ordered pairs (input and output)

40. 'Points' from side to side

41. No solution

42. Solid line

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

44. A=b - then b=a

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

46. A=a it is what it is

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


49. Hard - brackets

50. x-value because its value is given
