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






2. Shaded area






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






4. 'Points' from BOTTOM to TOP






5. 'Points' from side to side






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






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






8. Opposite - reciprocal slopes






9. Whats worth






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






11. Put is simplest form






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






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






14. Dotted line






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






16. A=a it is what it is






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






18. Shading goes down - or left






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






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






21. Hard - brackets






22. A=b - then ac=bc






23. Substitute AND simplify






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






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






26. No solution






27. e.g x






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






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






30. Set of ordered pairs (input and output)






31. 1 -2 -3...maybe 0






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






33. No fraction or decimal






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






35. x-value because its value is given






36. A=b - then b=a






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






38. mx+b=y






39. Horizontal line






40. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






41. ROW x COLUMN






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






43. Solve using every equation (use linear combination)

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






45. Vertical line






46. Intersecting points






47. Same slopes






48. Slope of 1/1 - through 0






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






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