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. Shading goes down - or left






2. Same slopes






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






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






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






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






7. Dotted line






8. A=a it is what it is






9. Set of ordered pairs (input and output)






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






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






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






13. Shaded area






14. No solution






15. Plug in vertices in objective function






16. Hard - brackets






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






18. Vertical line






19. 1 -2 -3...maybe 0






20. mx+b=y






21. Slope of 1/1 - through 0






22. Intersecting points






23. A=b - then b=a






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






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






26. Soft - parentheses






27. Shading goes up - or right






28. e.g x






29. No fraction or decimal






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






31. Solve using every equation (use linear combination)

32. Horizontal line






33. 'Points' from side to side






34. Solid line






35. Whats worth






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






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






38. Put is simplest form






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






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






41. x-value because its value is given






42. Substitute AND simplify






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






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






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






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






47. 'Points' from BOTTOM to TOP






48. [2x+3]=9 - [2x+3]=-9 write it both ways






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






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