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






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






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






4. No fraction or decimal






5. A=a it is what it is






6. 'Points' from side to side






7. Whats worth






8. Shading goes down - or left






9. e.g x






10. Solid line






11. Substitute AND simplify






12. Hard - brackets






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






14. One or more solutions






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






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






17. mx+b=y






18. [2x+3]=9 - [2x+3]=-9 write it both ways






19. x-value because its value is given






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






21. Intersecting points






22. Solve using every equation (use linear combination)

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






24. 1 -2 -3...maybe 0






25. Soft - parentheses






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






27. Horizontal line






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






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






30. Set of ordered pairs (input and output)






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






32. Original status a+0=a - ax1=a






33. A=b - then ac=bc






34. Vertical line






35. ROW x COLUMN






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






37. Shaded area






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






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






40. No solution






41. Dotted line






42. Plug in vertices in objective function






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






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






45. Shading goes up - or right






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






47. Same slopes






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






49. Opposite - reciprocal slopes






50. 'Points' from BOTTOM to TOP
