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. No fraction or decimal






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






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






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






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






6. Shaded area






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






8. Shading goes up - or right






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






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






11. A=b - then ac=bc






12. No solution






13. 1 -2 -3...maybe 0






14. 'Points' from side to side






15. Dotted line






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






17. Intersecting points






18. Same slopes






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






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






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






22. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






25. ROW x COLUMN






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






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






28. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






30. mx+b=y






31. A=a it is what it is






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






33. A=b - then b=a






34. Whats worth






35. Shading goes down - or left






36. Function whose graph is a line






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






38. Solve using every equation (use linear combination)

39. Solid line






40. Vertical line






41. Hard - brackets






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






43. One or more solutions






44. Set of ordered pairs (input and output)






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






46. Soft - parentheses






47. e.g x






48. Horizontal line






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






50. 'Points' from BOTTOM to TOP
