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. Dotted line






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






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






4. x-value because its value is given






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






6. Hard - brackets






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






8. Solve using every equation (use linear combination)

9. Shaded area






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

12. 'Points' from side to side






13. Solid line






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






15. No solution






16. mx+b=y






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






18. Shading goes up - or right






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






20. 1 -2 -3...maybe 0






21. Vertical line






22. Set of ordered pairs (input and output)






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






24. Shading goes down - or left






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






26. Put is simplest form






27. A=a it is what it is






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






29. Function whose graph is a line






30. Opposite - reciprocal slopes






31. Horizontal line






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






33. ROW x COLUMN






34. Substitute AND simplify






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






36. Soft - parentheses






37. Same slopes






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






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






40. One or more solutions






41. e.g x






42. Whats worth






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






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






45. Plug in vertices in objective function






46. 'Points' from BOTTOM to TOP






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






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






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






50. Intersecting points
