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. mx+b=y






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






3. Soft - parentheses






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






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






6. Horizontal line






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






8. Whats worth






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






10. Dotted line






11. Put is simplest form






12. Shading goes up - or right






13. 'Points' from side to side






14. Substitute AND simplify






15. ROW x COLUMN






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






17. One or more solutions






18. Set of ordered pairs (input and output)






19. [2x+3]=9 - [2x+3]=-9 write it both ways






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






21. Intersecting points






22. 1 -2 -3...maybe 0






23. Solid line






24. e.g x






25. Vertical line






26. A=b - then ac=bc






27. Same slopes






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






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






30. Hard - brackets






31. Shaded area






32. No fraction or decimal






33. 'Points' from BOTTOM to TOP






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






35. Solve using every equation (use linear combination)






36. No solution






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






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






39. Opposite - reciprocal slopes






40. A=a it is what it is






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






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






43. Slope of 1/1 - through 0






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






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






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






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






48. Shading goes down - or left






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






50. Function whose graph is a line
