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. Horizontal line






2. Whats worth






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






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






5. 1 -2 -3...maybe 0






6. x-value because its value is given






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






8. ROW x COLUMN






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






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






11. Solve using every equation (use linear combination)


12. No solution






13. Soft - parentheses






14. Shading goes down - or left






15. 'Points' from BOTTOM to TOP






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






17. Function whose graph is a line






18. Set of ordered pairs (input and output)






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






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






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






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






23. 'Points' from side to side






24. Slope of 1/1 - through 0






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






26. Vertical line






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






28. A=a it is what it is






29. Shading goes up - or right






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






31. Hard - brackets






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






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






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






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






36. Shaded area






37. Solid line






38. Opposite - reciprocal slopes






39. One or more solutions






40. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






42. mx+b=y






43. Plug in vertices in objective function






44. No fraction or decimal






45. A=b - then ac=bc






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






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






48. Dotted line






49. A=b - then b=a






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