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






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






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






4. Plug in vertices in objective function






5. Opposite - reciprocal slopes






6. Solid line






7. Function whose graph is a line






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






9. Shading goes down - or left






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






11. Whats worth






12. Slope of 1/1 - through 0






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






14. Soft - parentheses






15. Same slopes






16. Intersecting points






17. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






19. e.g x






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






21. One or more solutions






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






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






24. Shaded area






25. A=b - then b=a






26. x-value because its value is given






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






28. 1 -2 -3...maybe 0






29. 'Points' from BOTTOM to TOP






30. Substitute AND simplify






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






32. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






35. Set of ordered pairs (input and output)






36. Hard - brackets






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






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






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






40. Horizontal line






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






42. Dotted line






43. mx+b=y






44. 'Points' from side to side






45. A=a it is what it is






46. ROW x COLUMN






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






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






49. Solve using every equation (use linear combination)
