# Algebra Formulas

Subjects : math, algebra
Instructions:
• 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. Second step to linear combo. Fill in variable for whatever you solved for OR change equation to y= or x=

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

3. Shading goes up - or right

4. x-value because its value is given

5. A=a it is what it is

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

7. No solution

8. Vertical line

9. Whats worth

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

11. No fraction or decimal

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

13. Intersecting points

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

15. Function whose graph is a line

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

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

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

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

20. Put is simplest form

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

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

23. [2x+3]=9 - [2x+3]=-9 write it both ways

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

25. Plug in vertices in objective function

26. Same slopes

27. Set of ordered pairs (input and output)

28. Dotted line

29. One or more solutions

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

31. Solid line

32. Hard - brackets

33. Horizontal line

34. Slope of 1/1 - through 0

35. e.g x

36. Shading goes down - or left

37. Solve using every equation (use linear combination)

38. Soft - parentheses

39. A=b - then ac=bc

40. mx+b=y

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

42. 'Points' from side to side

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

44. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

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

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

47. ROW x COLUMN

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

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

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