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. e.g x






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






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






5. 'Points' from side to side






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






7. Soft - parentheses






8. Put is simplest form






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






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






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






12. Same slopes






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






14. Solve using every equation (use linear combination)






15. 'Points' from BOTTOM to TOP






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






17. Horizontal line






18. Plug in vertices in objective function






19. Hard - brackets






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






21. 1 -2 -3...maybe 0






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






23. A=b - then b=a






24. Shaded area






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






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






27. Vertical line






28. Opposite - reciprocal slopes






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






30. Shading goes down - or left






31. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






33. Whats worth






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






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






36. Set of ordered pairs (input and output)






37. No fraction or decimal






38. A=a it is what it is






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






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






41. [2x+3]=9 - [2x+3]=-9 write it both ways






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






43. Shading goes up - or right






44. Slope of 1/1 - through 0






45. Dotted line






46. Intersecting points






47. x-value because its value is given






48. Function whose graph is a line






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






50. A=b - then ac=bc
