# Algebra Formulas

**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. A=a it is what it is**

**2. Soft - parentheses**

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

**4. A=b - b=c - then a=c**

**5. Relations have all points in common e.g same line**

**6. 'Points' from side to side**

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

**8. Plug in vertices in objective function**

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

**10. Shading goes down - or left**

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

**12. Correct result - but doesn't work in equation**

**13. A=b - then b=a**

**14. f(x -y)=x + y**

**15. Same slopes**

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

**17. Shading goes up - or right**

**18. Whats worth**

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

**20. [2x+3]=9 - [2x+3]=-9 write it both ways**

**21. Opposite - reciprocal slopes**

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

**23. e.g x**

**24. Intersecting points**

**25. Dotted line**

**26. Solve using every equation (use linear combination)**

**27. ROW x COLUMN**

**28. One or more solutions**

**29. Hard - brackets**

**30. Undoes operation a+(-a)=0**

**31. If IxI>5 then x>5 or x<-5**

**32. A=b - then ac=bc**

**33. y-y{2}=m(x-x{2})**

**34. Put is simplest form**

**35. mx+b=y**

**36. Horizontal line**

**37. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3**

**38. Substitute AND simplify**

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

**40. x-value because its value is given**

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

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

**43. Vertical line**

**44. Shaded area**

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

**46. y-value - because its value depends on the x-value**

**47. Set of ordered pairs (input and output)**

**48. Change of order a+b+c=a+c+b**

**49. No fraction or decimal**

**50. 'Points' from BOTTOM to TOP**
