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. 'Points' from side to side






2. Horizontal line






3. 'Points' from BOTTOM to TOP






4. One or more solutions






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






6. [2x+3]=9 - [2x+3]=-9 write it both ways






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






8. A=b - then b=a






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






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






11. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






12. Same slopes






13. Shading goes up - or right






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






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






16. No solution






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






18. Dotted line






19. No fraction or decimal






20. Plug in vertices in objective function






21. Put is simplest form






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






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






24. mx+b=y






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






26. Function whose graph is a line






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






28. Soft - parentheses






29. x-value because its value is given






30. A=a it is what it is

32. Shading goes down - or left






33. Substitute AND simplify






34. Shaded area






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






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






37. Solid line






38. ROW x COLUMN






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






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






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






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






43. Set of ordered pairs (input and output)






44. Vertical line






45. Hard - brackets






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

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






49. Opposite - reciprocal slopes






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