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

2. Plug in vertices in objective function

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

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

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

7. Put is simplest form

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

9. Function whose graph is a line

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

11. A=a it is what it is

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

13. One or more solutions

14. Soft - parentheses

15. x-value because its value is given

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

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

19. [2x+3]=9 - [2x+3]=-9 write it both ways

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

21. Whats worth

22. Substitute AND simplify

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

24. Same slopes

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

26. e.g x

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

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

29. A=b - then ac=bc

30. Vertical line

31. Horizontal line

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

33. Solid line

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

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

36. Intersecting points

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

38. Shading goes down - or left

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

40. 'Points' from BOTTOM to TOP

41. mx+b=y

42. Dotted line

43. Shading goes up - or right

44. Slope of 1/1 - through 0

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

46. ROW x COLUMN

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

48. 'Points' from side to side

49. No solution

50. A=b - then b=a
