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. One or more solutions






2. Shaded area






3. Horizontal line






4. Shading goes down - or left






5. ROW x COLUMN






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






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






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






9. Put is simplest form






10. Slope of 1/1 - through 0






11. Function whose graph is a line






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






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






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






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






16. 'Points' from BOTTOM to TOP






17. [2x+3]=9 - [2x+3]=-9 write it both ways






18. A=a it is what it is






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






20. e.g x






21. Solid line






22. Plug in vertices in objective function






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






24. Hard - brackets






25. Soft - parentheses






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






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






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






29. x-value because its value is given






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






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






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






33. A=b - then ac=bc






34. A=b - then b=a






35. Whats worth






36. Intersecting points






37. Shading goes up - or right






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






39. mx+b=y






40. No fraction or decimal






41. No solution






42. Substitute AND simplify






43. 'Points' from side to side






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






45. Set of ordered pairs (input and output)






46. Same slopes






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






48. Vertical line






49. Solve using every equation (use linear combination)


50. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3
