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. A=b - then ac=bc






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






3. mx+b=y






4. Horizontal line






5. Shaded area






6. Slope of 1/1 - through 0






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






8. No solution






9. 'Points' from BOTTOM to TOP






10. Soft - parentheses






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






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






13. ROW x COLUMN






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






15. Hard - brackets






16. A=b - then b=a






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






18. Vertical line






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






20. Substitute AND simplify






21. Solve using every equation (use linear combination)


22. One or more solutions






23. Solid line






24. Shading goes up - or right






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






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






27. Set of ordered pairs (input and output)






28. A=a it is what it is






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






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






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






32. 1 -2 -3...maybe 0






33. No fraction or decimal






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






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






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






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






38. [2x+3]=9 - [2x+3]=-9 write it both ways






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






40. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






41. 'Points' from side to side






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






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






44. Whats worth






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






46. Put is simplest form






47. e.g x






48. x-value because its value is given






49. Same slopes






50. Intersecting points
