# 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. mx+b=y**

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

**3. Soft - parentheses**

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

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

**6. Horizontal line**

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

**8. Whats worth**

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

**10. Dotted line**

**11. Put is simplest form**

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

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

**14. Substitute AND simplify**

**15. ROW x COLUMN**

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

**17. One or more solutions**

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

**19. [2x+3]=9 - [2x+3]=-9 write it both ways**

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

**21. Intersecting points**

**22. 1 -2 -3...maybe 0**

**23. Solid line**

**24. e.g x**

**25. Vertical line**

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

**27. Same slopes**

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

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

**30. Hard - brackets**

**31. Shaded area**

**32. No fraction or decimal**

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

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

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

**36. No solution**

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

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

**39. Opposite - reciprocal slopes**

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

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

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

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

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

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

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

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

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

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

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