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. mx+b=y






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






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






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






5. x-value because its value is given






6. Whats worth






7. Opposite - reciprocal slopes






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






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






10. Set of ordered pairs (input and output)






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






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






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






14. Hard - brackets






15. Shading goes down - or left






16. Substitute AND simplify






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






18. Put is simplest form






19. No solution






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






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






22. e.g x






23. 'Points' from BOTTOM to TOP






24. A=a it is what it is






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






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






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






28. 1 -2 -3...maybe 0






29. Solve using every equation (use linear combination)


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






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






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






33. Dotted line






34. Horizontal line






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






36. A=b - then b=a






37. ROW x COLUMN






38. Same slopes






39. Plug in vertices in objective function






40. Slope of 1/1 - through 0






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






42. Shaded area






43. Shading goes up - or right






44. A=b - then ac=bc






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






46. Solid line






47. Intersecting points






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






49. One or more solutions






50. No fraction or decimal
