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






2. Horizontal line






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






4. Put is simplest form






5. mx+b=y






6. Set of ordered pairs (input and output)






7. 1 -2 -3...maybe 0






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






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






10. Solve using every equation (use linear combination)

11. Plug in vertices in objective function






12. Function whose graph is a line






13. Shading goes up - or right






14. Slope of 1/1 - through 0






15. A=b - then b=a






16. 'Points' from side to side






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






18. Vertical line






19. Soft - parentheses






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






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






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






23. No solution






24. Intersecting points






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






26. A=b - then ac=bc






27. Whats worth






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






29. Solid line






30. ROW x COLUMN






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






32. [2x+3]=9 - [2x+3]=-9 write it both ways






33. A=a it is what it is






34. Substitute AND simplify






35. 'Points' from BOTTOM to TOP






36. Shading goes down - or left






37. Hard - brackets






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






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






40. e.g x






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






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






43. Opposite - reciprocal slopes






44. Shaded area






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






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






47. Dotted line






48. No fraction or decimal






49. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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