Subjects : math, algebra
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. Opposite - reciprocal slopes






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






3. No fraction or decimal






4. e.g x






5. Plug in vertices in objective function






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






7. Put is simplest form






8. Solid line






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






10. Shading goes up - or right






11. Vertical line






12. ROW x COLUMN






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






14. Soft - parentheses






15. Shaded area






16. A=b - then b=a






17. Same slopes






18. Dotted line






19. A=a it is what it is






20. A=b - then ac=bc






21. 'Points' from side to side






22. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






25. Hard - brackets






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






27. Set of ordered pairs (input and output)






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






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






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






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






32. Intersecting points






33. Function whose graph is a line






34. Horizontal line






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






36. One or more solutions






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






38. 'Points' from BOTTOM to TOP






39. x-value because its value is given






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






41. [2x+3]=9 - [2x+3]=-9 write it both ways






42. Whats worth






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






44. mx+b=y






45. No solution






46. Solve using every equation (use linear combination)






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






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






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






50. Slope of 1/1 - through 0
