Subjects : math, algebra
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. Substitute AND simplify






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






3. Intersecting points






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






5. e.g x






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






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






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






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






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






11. 'Points' from BOTTOM to TOP






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






13. Whats worth






14. Plug in vertices in objective function






15. mx+b=y






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






17. Slope of 1/1 - through 0






18. Shaded area






19. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






22. A=b - then ac=bc






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






24. Solve using every equation (use linear combination)


25. ROW x COLUMN






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






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






28. One or more solutions






29. 1 -2 -3...maybe 0






30. No fraction or decimal






31. No solution






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






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






34. Shading goes up - or right






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






36. Put is simplest form






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






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






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






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






41. Set of ordered pairs (input and output)






42. Function whose graph is a line






43. Shading goes down - or left






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






45. Vertical line






46. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






47. Dotted line






48. Soft - parentheses






49. Hard - brackets






50. x-value because its value is given
