# 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. Opposite - reciprocal slopes

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

3. ROW x COLUMN

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

5. Substitute AND simplify

6. Hard - brackets

7. One or more solutions

8. 'Points' from side to side

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

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

11. A=a it is what it is

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

13. Shading goes down - or left

14. Set of ordered pairs (input and output)

15. Same slopes

16. No solution

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

19. e.g x

20. No fraction or decimal

21. Intersecting points

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

23. Put is simplest form

24. Solid line

25. Function whose graph is a line

26. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

28. Solve using every equation (use linear combination)

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

30. Whats worth

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

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

33. Horizontal line

34. A=b - then ac=bc

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

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

37. Plug in vertices in objective function

38. x-value because its value is given

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

40. Dotted line

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

42. Vertical line

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

44. Slope of 1/1 - through 0

45. A=b - then b=a

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

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

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

49. Soft - parentheses

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