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. Dotted line






2. Set of ordered pairs (input and output)






3. e.g x






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






5. 'Points' from side to side






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






7. x-value because its value is given






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






9. Vertical line






10. mx+b=y






11. Substitute AND simplify






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






13. Solid line






14. 'Points' from BOTTOM to TOP






15. Slope of 1/1 - through 0






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






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






18. A=a it is what it is






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






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






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






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






23. Horizontal line






24. Shading goes up - or right






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






26. Soft - parentheses






27. Same slopes






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






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






30. A=b - then b=a






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






32. [2x+3]=9 - [2x+3]=-9 write it both ways






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






34. Function whose graph is a line






35. ROW x COLUMN






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






37. Hard - brackets






38. Plug in vertices in objective function






39. Shaded area






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






41. Whats worth






42. Intersecting points






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






44. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






45. Solve using every equation (use linear combination)

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






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






48. One or more solutions






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






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