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. Same slopes






2. Horizontal line






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






4. Slope of 1/1 - through 0






5. One or more solutions






6. Put is simplest form






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






8. Hard - brackets






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






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






11. 'Points' from side to side






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






13. Solve using every equation (use linear combination)

14. [2x+3]=9 - [2x+3]=-9 write it both ways






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






16. Whats worth






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






18. Solid line






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






20. Plug in vertices in objective function






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






22. No solution






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






24. Shaded area






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






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






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






28. A=a it is what it is






29. x-value because its value is given






30. Intersecting points






31. 'Points' from BOTTOM to TOP






32. Shading goes up - or right






33. Soft - parentheses






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






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






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






37. A=b - then b=a






38. mx+b=y






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






40. A=b - then ac=bc






41. No fraction or decimal






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






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






44. ROW x COLUMN
