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. Horizontal line






2. No fraction or decimal






3. One or more solutions






4. Soft - parentheses






5. Hard - brackets






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






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






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






9. ROW x COLUMN






10. Slope of 1/1 - through 0






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






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






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






14. Dotted line






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






16. e.g x






17. 'Points' from side to side






18. Whats worth






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






20. x-value because its value is given






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






22. mx+b=y






23. Plug in vertices in objective function






24. 1 -2 -3...maybe 0






25. Substitute AND simplify






26. Shading goes up - or right






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






28. Shading goes down - or left






29. Same slopes






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






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






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






33. Vertical line






34. Opposite - reciprocal slopes






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






36. Put is simplest form






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






38. Set of ordered pairs (input and output)






39. No solution






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






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






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






43. Solid line






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






45. A=a it is what it is






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






47. Solve using every equation (use linear combination)

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






49. A=b - then b=a






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