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. A=b - then b=a






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






3. 'Points' from BOTTOM to TOP






4. Shaded area






5. Slope of 1/1 - through 0






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






7. Function whose graph is a line






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






9. A=a it is what it is






10. Horizontal line






11. Solid line






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






13. Opposite - reciprocal slopes






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






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






16. Same slopes






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






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






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






20. Set of ordered pairs (input and output)






21. No fraction or decimal






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






23. Plug in vertices in objective function






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






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






26. mx+b=y






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






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






29. Soft - parentheses






30. Vertical line






31. 1 -2 -3...maybe 0






32. 'Points' from side to side






33. A=b - then ac=bc






34. ROW x COLUMN






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






36. Put is simplest form






37. One or more solutions






38. Shading goes up - or right






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






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






41. x-value because its value is given






42. Dotted line






43. Intersecting points






44. Shading goes down - or left






45. e.g x






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






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






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






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






50. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3
