# 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. Intersecting points**

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

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

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

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

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

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

**8. Substitute AND simplify**

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

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

**11. [2x+3]=9 - [2x+3]=-9 write it both ways**

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

**13. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3**

**14. Solid line**

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

**16. Horizontal line**

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

**18. Same slopes**

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

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

**21. Whats worth**

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

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

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

**25. Plug in vertices in objective function**

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

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

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

**29. Shaded area**

**30. Soft - parentheses**

**31. Vertical line**

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

**33. No fraction or decimal**

**34. Dotted line**

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

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

**40. No solution**

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

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

**43. Put is simplest form**

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

**45. mx+b=y**

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

**47. One or more solutions**

**48. e.g x**

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

**50. Opposite - reciprocal slopes**
