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

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

**4. One or more solutions**

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

**6. Solid line**

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

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

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

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

**11. Put is simplest form**

**12. mx+b=y**

**13. Soft - parentheses**

**14. 'Points' from side to side**

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

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

**17. Opposite - reciprocal slopes**

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

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

**20. No solution**

**21. Same slopes**

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

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

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

**25. Horizontal line**

**26. Hard - brackets**

**27. ROW x COLUMN**

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

**29. Vertical line**

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

**31. No fraction or decimal**

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

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

**34. Intersecting points**

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

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

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

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

**39. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3**

**40. Dotted line**

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

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

**43. e.g x**

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

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

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

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

**48. Substitute AND simplify**

**49. Whats worth**

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