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






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






3. Slope of 1/1 - through 0






4. A=b - then b=a






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






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






7. mx+b=y






8. Same slopes






9. Plug in vertices in objective function






10. No fraction or decimal






11. 'Points' from BOTTOM to TOP






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






13. A=b - then ac=bc






14. Set of ordered pairs (input and output)






15. Shading goes up - or right






16. Dotted line






17. Function whose graph is a line






18. Hard - brackets






19. Whats worth






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






21. Substitute AND simplify






22. Put is simplest form






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






24. Horizontal line






25. ROW x COLUMN






26. Intersecting points






27. Opposite - reciprocal slopes






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






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






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






31. Soft - parentheses






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






33. A=a it is what it is






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






35. e.g x






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






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






38. x-value because its value is given






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






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






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






42. Solid line






43. 1 -2 -3...maybe 0






44. Shading goes down - or left






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






46. 'Points' from side to side






47. Vertical line






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






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






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