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. A=b - then b=a






2. Set of ordered pairs (input and output)






3. Shaded area






4. Soft - parentheses






5. Slope of 1/1 - through 0






6. 1 -2 -3...maybe 0






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






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






9. No fraction or decimal






10. Hard - brackets






11. Same slopes






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






13. 'Points' from BOTTOM to TOP






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






15. One or more solutions






16. A=a it is what it is






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






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






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






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






21. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






23. Whats worth






24. Substitute AND simplify






25. Plug in vertices in objective function






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






27. No solution






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






29. A=b - then ac=bc






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






31. Function whose graph is a line






32. e.g x






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






34. Shading goes down - or left






35. Dotted line






36. x-value because its value is given






37. Horizontal line






38. Solve using every equation (use linear combination)

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






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






41. Opposite - reciprocal slopes






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






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






44. Shading goes up - or right






45. 'Points' from side to side






46. ROW x COLUMN






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






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






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






50. Vertical line
