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

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

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

4. One or more solutions

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

6. Solid line

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

8. Function whose graph is a line

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

10. 1 -2 -3...maybe 0

11. Put is simplest form

12. mx+b=y

13. Soft - parentheses

14. 'Points' from side to side

15. A=a it is what it is

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

17. Opposite - reciprocal slopes

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

19. Shading goes down - or left

20. No solution

21. Same slopes

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

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

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

25. Horizontal line

26. Hard - brackets


28. A=b - then b=a

29. Vertical line

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

31. No fraction or decimal

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

33. x-value because its value is given

34. Intersecting points

35. A=b - then ac=bc

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

37. Shading goes up - or right

38. Solve using every equation (use linear combination)

39. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

40. Dotted line

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

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

43. e.g x

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

45. Plug in vertices in objective function

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

47. Set of ordered pairs (input and output)

48. Substitute AND simplify

49. Whats worth

50. Slope of 1/1 - through 0
