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






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






3. Slope of 1/1 - through 0






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






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






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






7. A=a it is what it is






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






9. A=b - then b=a






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






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






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






13. Hard - brackets






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






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






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






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






18. Put is simplest form






19. No solution






20. A=b - then ac=bc






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






22. x-value because its value is given






23. No fraction or decimal






24. ROW x COLUMN






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






26. 'Points' from side to side






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






28. Solid line






29. Shaded area






30. One or more solutions






31. Solve using every equation (use linear combination)


32. Dotted line






33. Plug in vertices in objective function






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






35. Opposite - reciprocal slopes






36. Shading goes up - or right






37. e.g x






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






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






40. Same slopes






41. Soft - parentheses






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






43. Substitute AND simplify






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






45. Vertical line






46. Whats worth






47. mx+b=y






48. Horizontal line






49. [2x+3]=9 - [2x+3]=-9 write it both ways






50. Shading goes down - or left
