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. 1 -2 -3...maybe 0






2. Dotted line






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






4. Whats worth






5. Slope of 1/1 - through 0






6. Shading goes down - or left






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






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






9. Vertical line






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






11. ROW x COLUMN






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






13. Same slopes






14. Opposite - reciprocal slopes






15. [2x+3]=9 - [2x+3]=-9 write it both ways






16. Horizontal line






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






18. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






19. mx+b=y






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






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






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






23. Put is simplest form






24. e.g x






25. A=a it is what it is






26. Solid line






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






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






29. No fraction or decimal






30. Function whose graph is a line






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






32. Plug in vertices in objective function






33. One or more solutions






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






35. 'Points' from side to side






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






37. Solve using every equation (use linear combination)

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






40. Set of ordered pairs (input and output)






41. No solution






42. A=b - then b=a






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






44. A=b - then ac=bc






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






46. Intersecting points






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






48. Shaded area






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






50. Hard - brackets
