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






2. Set of ordered pairs (input and output)






3. Dotted line






4. Same slopes






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






6. Shading goes down - or left






7. 'Points' from side to side






8. Shading goes up - or right






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






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






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






12. Substitute AND simplify






13. mx+b=y






14. Opposite - reciprocal slopes






15. A=a it is what it is






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






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. f(x -y)=x + y






19. Whats worth






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






21. Plug in vertices in objective function






22. [2x+3]=9 - [2x+3]=-9 write it both ways






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






24. ROW x COLUMN






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






26. No solution






27. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






28. Solid line






29. No fraction or decimal






30. Hard - brackets






31. A=b - then b=a






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






33. Slope of 1/1 - through 0






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






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






36. 1 -2 -3...maybe 0






37. 'Points' from BOTTOM to TOP






38. Soft - parentheses






39. One or more solutions






40. A=b - then ac=bc






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






42. Solve using every equation (use linear combination)


43. e.g x






44. Intersecting points






45. Put is simplest form






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






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






48. Function whose graph is a line






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






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