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. Solid line






2. Horizontal line






3. A=a it is what it is






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






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






6. Plug in vertices in objective function






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






8. Whats worth






9. Same slopes






10. Intersecting points






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






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






13. Shaded area






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






15. Shading goes down - or left






16. No fraction or decimal






17. 1 -2 -3...maybe 0






18. One or more solutions






19. Hard - brackets






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






21. Opposite - reciprocal slopes






22. Dotted line






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






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






25. A=b - then ac=bc






26. Put is simplest form






27. Substitute AND simplify






28. [2x+3]=9 - [2x+3]=-9 write it both ways






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






30. Shading goes up - or right






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






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






33. Soft - parentheses






34. Vertical line






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






36. x-value because its value is given






37. 'Points' from side to side






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






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






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






41. Set of ordered pairs (input and output)






42. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






45. Function whose graph is a line






46. A=b - then b=a






47. mx+b=y






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






49. ROW x COLUMN






50. Slope of 1/1 - through 0
