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. Solve using every equation (use linear combination)


2. No solution






3. Same slopes






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






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






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






7. Plug in vertices in objective function






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






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






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






11. Put is simplest form






12. No fraction or decimal






13. Dotted line






14. x-value because its value is given






15. One or more solutions






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






17. Hard - brackets






18. 1 -2 -3...maybe 0






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






20. Function whose graph is a line






21. Vertical line






22. Set of ordered pairs (input and output)






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






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






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






26. Intersecting points






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






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






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






30. Shading goes up - or right






31. Shading goes down - or left






32. Substitute AND simplify






33. 'Points' from BOTTOM to TOP






34. A=b - then b=a






35. A=b - then ac=bc






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






37. A=a it is what it is






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






39. [2x+3]=9 - [2x+3]=-9 write it both ways






40. Opposite - reciprocal slopes






41. Shaded area






42. Horizontal line






43. Slope of 1/1 - through 0






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






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

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






48. mx+b=y






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






50. Whats worth
