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. Undoes operation a+(-a)=0






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






3. x-value because its value is given






4. Same slopes






5. Shading goes down - or left






6. Substitute AND simplify






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






8. Intersecting points






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






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






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






12. Vertical line






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






14. Opposite - reciprocal slopes






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






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






17. mx+b=y






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






19. One or more solutions






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






21. No solution






22. Function whose graph is a line






23. Slope of 1/1 - through 0






24. 'Points' from side to side






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






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






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






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






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






30. A=b - then ac=bc






31. A=b - then b=a






32. Set of ordered pairs (input and output)






33. ROW x COLUMN






34. Put is simplest form






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






36. 'Points' from BOTTOM to TOP






37. Shaded area






38. Hard - brackets






39. Soft - parentheses






40. e.g x






41. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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






44. Dotted line






45. Solid line






46. Solve using every equation (use linear combination)


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






48. 1 -2 -3...maybe 0






49. No fraction or decimal






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