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. Function whose graph is a line






2. ROW x COLUMN






3. Shading goes down - or left






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






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






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






7. Shaded area






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






9. Whats worth






10. Solve using every equation (use linear combination)

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






12. e.g x






13. A=a it is what it is






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






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






16. 'Points' from BOTTOM to TOP






17. Put is simplest form






18. No fraction or decimal






19. Same slopes






20. 'Points' from side to side






21. No solution






22. One or more solutions






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






24. Plug in vertices in objective function






25. Horizontal line






26. A=b - then ac=bc






27. Solid line






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






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






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






31. A=b - then b=a






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






33. Intersecting points






34. mx+b=y






35. Substitute AND simplify






36. Soft - parentheses






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






38. x-value because its value is given






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






40. Dotted line






41. Vertical line






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






43. Hard - brackets






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






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






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






47. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






50. Set of ordered pairs (input and output)
