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. Set of ordered pairs (input and output)






2. mx+b=y






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






4. Whats worth






5. Soft - parentheses






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






7. Shaded area






8. Plug in vertices in objective function






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






10. 1 -2 -3...maybe 0






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






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






13. No solution






14. A=b - then b=a






15. Solid line






16. Slope of 1/1 - through 0






17. Shading goes up - or right






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






19. x-value because its value is given






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






21. No fraction or decimal






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






23. Put is simplest form






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






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






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






27. Function whose graph is a line






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






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






30. Substitute AND simplify






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






32. Opposite - reciprocal slopes






33. Hard - brackets






34. Dotted line






35. One or more solutions






36. Vertical line






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






38. Same slopes






39. Horizontal line






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






41. e.g x






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






43. A=b - then ac=bc






44. Shading goes down - or left






45. 'Points' from BOTTOM to TOP






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






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






48. ROW x COLUMN






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






50. A=a it is what it is
