# 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. No fraction or decimal**

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

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

**5. Soft - parentheses**

**6. Put is simplest form**

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

**8. mx+b=y**

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

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

**11. 'Points' from side to side**

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

**13. Shaded area**

**14. Vertical line**

**15. 1 -2 -3...maybe 0**

**16. Intersecting points**

**17. Horizontal line**

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

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

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

**21. No solution**

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

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

**24. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3**

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

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

**27. Opposite - reciprocal slopes**

**28. e.g x**

**29. Dotted line**

**30. Whats worth**

**31. Solid line**

**32. One or more solutions**

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

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

**35. Substitute AND simplify**

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

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

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

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

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

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

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

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

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

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

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

**47. Hard - brackets**

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

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

**50. Same slopes**
