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 ac=bc






2. e.g x






3. No fraction or decimal






4. Function whose graph is a line






5. 'Points' from BOTTOM to TOP






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






7. x-value because its value is given






8. mx+b=y






9. Put is simplest form






10. No solution






11. Intersecting points






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






13. Slope of 1/1 - through 0






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






15. Substitute AND simplify






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






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






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






19. Vertical line






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






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






22. Whats worth






23. Shading goes up - or right






24. Horizontal line






25. Plug in vertices in objective function






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






27. Solid line






28. Shaded area






29. Same slopes






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






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






32. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






35. A=b - then b=a






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






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






38. 1 -2 -3...maybe 0






39. One or more solutions






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






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






42. Solve using every equation (use linear combination)


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






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






45. Set of ordered pairs (input and output)






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






47. Soft - parentheses






48. 'Points' from side to side






49. A=a it is what it is






50. Hard - brackets
