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 to obvious but it re-enforces your understanding as you take the test each time.
1. Second step to linear combo. Fill in variable for whatever you solved for OR change equation to y= or x=






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






3. 'Points' from BOTTOM to TOP






4. [2x+3]=9 - [2x+3]=-9 write it both ways






5. Set of ordered pairs (input and output)






6. Function whose graph is a line






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






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






9. Put is simplest form






10. x-value because its value is given






11. Plug in vertices in objective function






12. Opposite - reciprocal slopes






13. ROW x COLUMN






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






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






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






17. Shading goes down - or left






18. No solution






19. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






21. Shading goes up - or right






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






23. Soft - parentheses






24. e.g x






25. Solve using every equation (use linear combination)






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






27. Intersecting points






28. 'Points' from side to side






29. One or more solutions






30. Vertical line






31. Shaded area






32. Substitute AND simplify






33. 1 -2 -3...maybe 0






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






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






36. A=b - then b=a






37. Slope of 1/1 - through 0






38. A=a it is what it is






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






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






41. Solid line






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






43. Dotted line






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






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






46. Same slopes






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






48. No fraction or decimal






49. Hard - brackets






50. Horizontal line
