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 (2 -3) in x+1=y - 2+1=3






2. A=a it is what it is






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






4. Substitute AND simplify






5. No fraction or decimal






6. Plug in vertices in objective function






7. Dotted line






8. Slope of 1/1 - through 0






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






10. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






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






14. Horizontal line






15. Intersecting points






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






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






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






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






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






21. Same slopes






22. Function whose graph is a line






23. 1 -2 -3...maybe 0






24. Shading goes up - or right






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






26. Set of ordered pairs (input and output)






27. Solid line






28. [2x+3]=9 - [2x+3]=-9 write it both ways






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






30. Shading goes down - or left






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






32. Vertical line






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






34. Soft - parentheses






35. Hard - brackets






36. Whats worth






37. ROW x COLUMN






38. e.g x






39. x-value because its value is given






40. Put is simplest form






41. 'Points' from BOTTOM to TOP






42. A=b - then b=a






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






44. A=b - then ac=bc






45. One or more solutions






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






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






48. 'Points' from side to side






49. Opposite - reciprocal slopes






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