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






2. Same slopes






3. Hard - brackets






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






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






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






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






8. Substitute AND simplify






9. Opposite - reciprocal slopes






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






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






12. 1 -2 -3...maybe 0






13. Put is simplest form






14. Intersecting points






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






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






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






18. [2x+3]=9 - [2x+3]=-9 write it both ways






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






20. Shading goes up - or right






21. Vertical line






22. mx+b=y






23. ROW x COLUMN






24. No fraction or decimal






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






26. Set of ordered pairs (input and output)






27. Shaded area






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






29. Soft - parentheses






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






31. A=b - then ac=bc






32. 'Points' from side to side






33. A=a it is what it is






34. 'Points' from BOTTOM to TOP






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






36. Function whose graph is a line






37. A=b - then b=a






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






39. Shading goes down - or left






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






41. x-value because its value is given






42. No solution






43. Whats worth






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






45. Plug in vertices in objective function






46. Solid line






47. Horizontal line






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






49. Dotted line






50. Slope of 1/1 - through 0
