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. 1 -2 -3...maybe 0






2. Hard - brackets






3. 'Points' from side to side






4. Whats worth






5. Same slopes






6. Slope of 1/1 - through 0






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






8. A=b - then ac=bc






9. Shading goes down - or left






10. No fraction or decimal






11. Set of ordered pairs (input and output)






12. 'Points' from BOTTOM to TOP






13. Shading goes up - or right






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






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






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






17. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






18. Vertical line






19. No solution






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






21. ROW x COLUMN






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






23. e.g x






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






25. Solve using every equation (use linear combination)

26. Dotted line






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






28. mx+b=y






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






30. Opposite - reciprocal slopes






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






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






33. [2x+3]=9 - [2x+3]=-9 write it both ways






34. Soft - parentheses






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






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






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






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






39. Intersecting points






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






41. Plug in vertices in objective function






42. A=a it is what it is






43. Function whose graph is a line






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






45. A=b - then b=a






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






47. Substitute AND simplify






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






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






50. x-value because its value is given
