Algebra Formulas

Subjects : math, algebra
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. ROW x COLUMN






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






3. Slope of 1/1 - through 0






4. y-value - because its value depends on the x-value






5. Intersecting points






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






7. mx+b=y






8. Undoes operation a+(-a)=0






9. A=b - then ac=bc






10. Hard - brackets






11. y-y{2}=m(x-x{2})






12. Dotted line






13. 'Points' from BOTTOM to TOP






14. Change of order a+b+c=a+c+b






15. Same slopes






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






17. x-value because its value is given






18. 'Points' from side to side






19. Solve for (3x-4)(x+5)






20. Solve using every equation (use linear combination)

21. 1 -2 -3...maybe 0






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






23. Shading goes down - or left






24. No fraction or decimal






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






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






27. Change of grouping a+(b+c)=(a+b)+c






28. A=a it is what it is






29. One or more solutions






30. If IxI>5 then x>5 or x<-5






31. Opposite - reciprocal slopes






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






33. Plug in vertices in objective function






34. Soft - parentheses






35. Substitute AND simplify






36. A=b - then b=a






37. Function whose graph is a line






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






39. Set of ordered pairs (input and output)






40. Relations have all points in common e.g same line






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






42. e.g x






43. Shading goes up - or right






44. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






45. Horizontal line






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






47. Put is simplest form






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






49. Vertical line






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