# 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. Put is simplest form**

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

**3. Intersecting points**

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

**5. Substitute AND simplify**

**6. Hard - brackets**

**7. Slope of 1/1 - through 0**

**8. Function whose graph is a line**

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

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

**11. Vertical line**

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

**13. 'Points' from side to side**

**14. mx+b=y**

**15. No fraction or decimal**

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

**17. Whats worth**

**18. e.g x**

**19. Dotted line**

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

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

**22. ROW x COLUMN**

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

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

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

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

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

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

**29. Horizontal line**

**30. Solid line**

**31. Same slopes**

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

**33. Shaded area**

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

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

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

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

**38. Plug in vertices in objective function**

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

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

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

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

**43. [2x+3]=9 - [2x+3]=-9 write it both ways**

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

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

**46. One or more solutions**

**47. Original status a+0=a - ax1=a**

**48. No solution**

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

**50. Soft - parentheses**
