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. Soft - parentheses






2. Substitute AND simplify






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






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






5. Opposite - reciprocal slopes






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






7. No fraction or decimal






8. Put is simplest form






9. Hard - brackets






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






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






12. 1 -2 -3...maybe 0






13. 'Points' from BOTTOM to TOP






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






15. A=b - then b=a






16. Same slopes






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






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






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






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






21. Whats worth






22. 'Points' from side to side






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






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






25. Solid line






26. One or more solutions






27. ROW x COLUMN






28. mx+b=y






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






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






31. Set of ordered pairs (input and output)






32. Plug in vertices in objective function






33. Horizontal line






34. x-value because its value is given






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






36. Dotted line






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






38. Function whose graph is a line






39. Slope of 1/1 - through 0






40. Intersecting points






41. e.g x






42. No solution






43. Vertical line






44. Shading goes down - or left






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






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






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






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






49. [2x+3]=9 - [2x+3]=-9 write it both ways






50. A=a it is what it is
