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. Vertical line






2. Set of ordered pairs (input and output)






3. x-value because its value is given






4. Slope of 1/1 - through 0






5. Solid line






6. 1 -2 -3...maybe 0






7. [2x+3]=9 - [2x+3]=-9 write it both ways






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






9. Shaded area






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






11. Intersecting points






12. mx+b=y






13. Horizontal line






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






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






16. Function whose graph is a line






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






18. No fraction or decimal






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






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






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






22. A=a it is what it is






23. Substitute AND simplify






24. Shading goes up - or right






25. 'Points' from BOTTOM to TOP






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






27. A=b - then ac=bc






28. No solution






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






30. A=b - then b=a






31. Opposite - reciprocal slopes






32. Dotted line






33. f(x -y)=x + y






34. Put is simplest form






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






36. 'Points' from side to side






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






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






39. e.g x






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






41. ROW x COLUMN






42. Hard - brackets






43. Same slopes






44. Plug in vertices in objective function






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






46. Shading goes down - or left






47. Solve using every equation (use linear combination)

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






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






50. Soft - parentheses
