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






2. x-value because its value is given






3. ROW x COLUMN






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






5. Shaded area






6. 'Points' from BOTTOM to TOP






7. Slope of 1/1 - through 0






8. A=b - then ac=bc






9. Shading goes up - or right






10. Horizontal line






11. Set of ordered pairs (input and output)






12. mx+b=y






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






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






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






16. Substitute AND simplify






17. 1 -2 -3...maybe 0






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






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






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






21. e.g x






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






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






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






25. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






26. Hard - brackets






27. Shading goes down - or left






28. Vertical line






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






30. Intersecting points






31. 'Points' from side to side






32. No fraction or decimal






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






34. Dotted line






35. Solid line






36. Soft - parentheses






37. Same slopes






38. Opposite - reciprocal slopes






39. One or more solutions






40. Put is simplest form






41. Function whose graph is a line






42. A=a it is what it is






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






44. Solve using every equation (use linear combination)

45. Plug in vertices in objective function






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






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






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






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






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