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






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






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






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






5. Slope of 1/1 - through 0






6. Function whose graph is a line






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






8. Substitute AND simplify






9. Horizontal line






10. Whats worth






11. Dotted line






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






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






14. Opposite - reciprocal slopes






15. 1 -2 -3...maybe 0






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






17. Solid line






18. No solution






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






20. Intersecting points






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






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






23. One or more solutions






24. Shading goes up - or right






25. Plug in vertices in objective function






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






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






28. A=b - then ac=bc






29. Vertical line






30. 'Points' from BOTTOM to TOP






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






32. No fraction or decimal






33. 'Points' from side to side






34. mx+b=y






35. [2x+3]=9 - [2x+3]=-9 write it both ways






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






37. A=a it is what it is






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






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






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






41. Put is simplest form






42. Shaded area






43. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






44. e.g x






45. Soft - parentheses






46. A=b - then b=a






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






48. Shading goes down - or left






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






50. ROW x COLUMN
