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






2. Shading goes down - or left






3. Horizontal line






4. Intersecting points






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






6. Soft - parentheses






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






8. Solve using every equation (use linear combination)

10. 'Points' from BOTTOM to TOP






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






12. Plug in vertices in objective function






13. Whats worth






14. 1 -2 -3...maybe 0






15. Dotted line






16. Set of ordered pairs (input and output)






17. A=b - then b=a






18. mx+b=y






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






20. Vertical line






21. No fraction or decimal






22. Slope of 1/1 - through 0






23. Opposite - reciprocal slopes






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






25. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






28. Shaded area






29. Put is simplest form






30. Function whose graph is a line






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






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






33. Same slopes






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






35. 'Points' from side to side






36. No solution






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






38. A=a it is what it is






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






40. x-value because its value is given






41. Substitute AND simplify






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






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






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






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






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






47. One or more solutions






48. e.g x






49. Shading goes up - or right






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