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

**2. Same slopes**

**3. Hard - brackets**

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

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

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

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

**8. Substitute AND simplify**

**9. Opposite - reciprocal slopes**

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

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

**12. 1 -2 -3...maybe 0**

**13. Put is simplest form**

**14. Intersecting points**

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

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

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

**18. [2x+3]=9 - [2x+3]=-9 write it both ways**

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

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

**21. Vertical line**

**22. mx+b=y**

**23. ROW x COLUMN**

**24. No fraction or decimal**

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

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

**27. Shaded area**

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

**29. Soft - parentheses**

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

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

**32. 'Points' from side to side**

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

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

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

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

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

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

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

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

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

**42. No solution**

**43. Whats worth**

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

**45. Plug in vertices in objective function**

**46. Solid line**

**47. Horizontal line**

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

**49. Dotted line**

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