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 ordered pairs (input and output)






2. A=b - then ac=bc






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






4. No solution






5. 'Points' from BOTTOM to TOP






6. Slope of 1/1 - through 0






7. Opposite - reciprocal slopes






8. 1 -2 -3...maybe 0






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






10. e.g x






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






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






13. Shaded area






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






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






16. mx+b=y






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






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






19. Put is simplest form






20. Soft - parentheses






21. No fraction or decimal






22. A=a it is what it is






23. Intersecting points






24. Vertical line






25. x-value because its value is given






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






27. Shading goes up - or right






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






29. ROW x COLUMN






30. Dotted line






31. Same slopes






32. Hard - brackets






33. Solid line






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






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






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






37. Shading goes down - or left






38. Substitute AND simplify






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






40. Function whose graph is a line






41. Plug in vertices in objective function






42. 'Points' from side to side






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






44. [2x+3]=9 - [2x+3]=-9 write it both ways






45. Horizontal line






46. Whats worth






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






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






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






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