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. Horizontal line






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






3. No fraction or decimal






4. mx+b=y






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






6. Slope of 1/1 - through 0






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






8. Solid line






9. A=b - then ac=bc






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






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






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






13. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






14. Opposite - reciprocal slopes






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






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






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






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






19. A=a it is what it is






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






21. [2x+3]=9 - [2x+3]=-9 write it both ways






22. ROW x COLUMN






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






24. Hard - brackets






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






26. One or more solutions






27. Solve using every equation (use linear combination)


28. Dotted line






29. e.g x






30. Plug in vertices in objective function






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






32. Function whose graph is a line






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






34. 1 -2 -3...maybe 0






35. Intersecting points






36. Whats worth






37. x-value because its value is given






38. Soft - parentheses






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






40. 'Points' from BOTTOM to TOP






41. Substitute AND simplify






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






43. Shading goes up - or right






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






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






46. Vertical line






47. Shaded area






48. 'Points' from side to side






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






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