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 fraction or decimal






2. Opposite - reciprocal slopes






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






4. 'Points' from side to side






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






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






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






8. Shading goes up - or right






9. Intersecting points






10. 'Points' from BOTTOM to TOP






11. Soft - parentheses






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






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






14. ROW x COLUMN






15. One or more solutions






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






17. [2x+3]=9 - [2x+3]=-9 write it both ways






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






19. A=b - then b=a






20. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






21. A=a it is what it is






22. Shaded area






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






24. e.g x






25. Same slopes






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






27. Dotted line






28. No solution






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






30. Set of ordered pairs (input and output)






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






32. Function whose graph is a line






33. Solve using every equation (use linear combination)

34. x-value because its value is given






35. Whats worth






36. A=b - then ac=bc






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






38. Substitute AND simplify






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






40. Solid line






41. Hard - brackets






42. Plug in vertices in objective function






43. Vertical line






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






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






46. Slope of 1/1 - through 0






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






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






49. Shading goes down - or left






50. mx+b=y
