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






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






3. x-value because its value is given






4. Shading goes up - or right






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






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






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






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






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






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






11. Hard - brackets






12. Shaded area






13. mx+b=y






14. Soft - parentheses






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






16. 1 -2 -3...maybe 0






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






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






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






20. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






21. Shading goes down - or left






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






23. Whats worth






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






25. Horizontal line






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






27. Same slopes






28. Opposite - reciprocal slopes






29. One or more solutions






30. Intersecting points






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






32. Put is simplest form






33. Vertical line






34. Slope of 1/1 - through 0






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






36. 'Points' from side to side






37. No solution






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






39. Solid line






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






41. Function whose graph is a line






42. Dotted line






43. Set of ordered pairs (input and output)






44. ROW x COLUMN






45. No fraction or decimal






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






47. Plug in vertices in objective function






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






49. A=a it is what it is






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