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. Whats worth






2. Shaded area






3. Shading goes up - or right






4. A=b - then b=a






5. [2x+3]=9 - [2x+3]=-9 write it both ways






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






7. Plug in vertices in objective function






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






9. Dotted line






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






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






12. 'Points' from side to side






13. 1 -2 -3...maybe 0






14. Same slopes






15. Slope of 1/1 - through 0






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






17. 'Points' from BOTTOM to TOP






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






19. x-value because its value is given






20. Substitute AND simplify






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






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






23. Soft - parentheses






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






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






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






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






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






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






30. Intersecting points






31. mx+b=y






32. Function whose graph is a line






33. One or more solutions

36. Vertical line






37. Put is simplest form






38. A=a it is what it is






39. Horizontal line






40. No solution






41. Solve using every equation (use linear combination)






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






43. A=b - then ac=bc






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






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






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






47. Set of ordered pairs (input and output)






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






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






50. Opposite - reciprocal slopes
