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






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






3. Shading goes up - or right






4. x-value because its value is given






5. A=a it is what it is






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






7. No solution






8. Vertical line






9. Whats worth






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






11. No fraction or decimal






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






13. Intersecting points






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






15. Function whose graph is a line






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






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






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






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






20. Put is simplest form






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






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






23. [2x+3]=9 - [2x+3]=-9 write it both ways






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






25. Plug in vertices in objective function






26. Same slopes






27. Set of ordered pairs (input and output)






28. Dotted line






29. One or more solutions






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






31. Solid line






32. Hard - brackets






33. Horizontal line






34. Slope of 1/1 - through 0






35. e.g x






36. Shading goes down - or left






37. Solve using every equation (use linear combination)






38. Soft - parentheses






39. A=b - then ac=bc






40. mx+b=y






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






42. 'Points' from side to side






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






44. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






47. ROW x COLUMN






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






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






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