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






3. Hard - brackets






4. Slope of 1/1 - through 0






5. Shading goes down - or left






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






7. x-value because its value is given






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






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






10. One or more solutions






11. mx+b=y






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






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






14. Function whose graph is a line






15. [2x+3]=9 - [2x+3]=-9 write it both ways






16. Intersecting points






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






18. Put is simplest form






19. A=a it is what it is






20. Substitute AND simplify






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






22. Vertical line






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






24. ROW x COLUMN






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






26. 'Points' from BOTTOM to TOP






27. No fraction or decimal






28. Soft - parentheses






29. A=b - then b=a






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






31. Solve using every equation (use linear combination)


32. Opposite - reciprocal slopes






33. Shading goes up - or right






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






35. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






36. Same slopes






37. 'Points' from side to side






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






39. No solution






40. Horizontal line






41. Solid line






42. Whats worth






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






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






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






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






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






48. e.g x






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






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