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. No solution






2. Slope of 1/1 - through 0






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






4. mx+b=y






5. e.g x






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






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






8. Whats worth






9. Horizontal line






10. One or more solutions






11. Intersecting points






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






13. A=b - then ac=bc






14. 'Points' from side to side






15. No fraction or decimal






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






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






18. Shading goes up - or right






19. Dotted line






20. Same slopes






21. x-value because its value is given






22. 1 -2 -3...maybe 0






23. Substitute AND simplify






24. Shaded area






25. A=a it is what it is






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






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






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






29. Opposite - reciprocal slopes






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






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






32. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






33. Vertical line






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






35. Shading goes down - or left






36. A=b - then b=a






37. Put is simplest form






38. ROW x COLUMN






39. Set of ordered pairs (input and output)






40. [2x+3]=9 - [2x+3]=-9 write it both ways






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






42. Function whose graph is a line






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






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






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






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






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






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






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






50. Plug in vertices in objective function
