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. Solid line






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






3. A=b - then ac=bc






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






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






6. No fraction or decimal






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






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






9. Dotted line






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






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






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






13. Shaded area






14. mx+b=y






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






16. Whats worth






17. ROW x COLUMN






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






19. Horizontal line






20. Solve using every equation (use linear combination)

21. Shading goes up - or right






22. Function whose graph is a line






23. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






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






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






28. A=b - then b=a






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






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






31. Intersecting points






32. Slope of 1/1 - through 0






33. e.g x






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






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






36. No solution






37. Soft - parentheses






38. A=a it is what it is






39. Hard - brackets






40. Opposite - reciprocal slopes






41. Same slopes






42. x-value because its value is given






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






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






45. [2x+3]=9 - [2x+3]=-9 write it both ways






46. One or more solutions






47. 'Points' from BOTTOM to TOP






48. Set of ordered pairs (input and output)






49. Substitute AND simplify






50. Vertical line
