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. 'Points' from BOTTOM to TOP






2. One or more solutions






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






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






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






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






7. No fraction or decimal






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






9. ROW x COLUMN






10. 'Points' from side to side






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






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






13. Hard - brackets






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






15. Slope of 1/1 - through 0






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






17. Intersecting points






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






19. Horizontal line






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






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






22. Solid line






23. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






24. Whats worth






25. Put is simplest form






26. Opposite - reciprocal slopes






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






28. Solve using every equation (use linear combination)


29. [2x+3]=9 - [2x+3]=-9 write it both ways






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






31. A=b - then b=a






32. 1 -2 -3...maybe 0






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






34. Same slopes






35. Function whose graph is a line






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






37. Plug in vertices in objective function






38. x-value because its value is given






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






40. Dotted line






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






42. mx+b=y






43. A=b - then ac=bc






44. Vertical line






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






46. Substitute AND simplify






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






48. Set of ordered pairs (input and output)






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






50. Shading goes down - or left
