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. No fraction or decimal






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






3. Opposite - reciprocal slopes






4. Substitute AND simplify






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






6. Intersecting points






7. Horizontal line






8. Shading goes up - or right






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






10. mx+b=y






11. Hard - brackets






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






13. [2x+3]=9 - [2x+3]=-9 write it both ways






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






15. Slope of 1/1 - through 0






16. Put is simplest form






17. No solution






18. A=b - then ac=bc






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






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






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






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






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






24. Solve using every equation (use linear combination)

25. Function whose graph is a line






26. Shaded area






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






28. 'Points' from BOTTOM to TOP






29. Plug in vertices in objective function






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






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






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






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






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






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






36. 1 -2 -3...maybe 0






37. A=b - then b=a






38. e.g x






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






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






41. One or more solutions






42. A=a it is what it is






43. 'Points' from side to side






44. Shading goes down - or left






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






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






47. ROW x COLUMN






48. Dotted line






49. Set of ordered pairs (input and output)






50. Soft - parentheses
