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






2. Whats worth






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






4. Intersecting points






5. mx+b=y






6. Solid line






7. Put is simplest form






8. Hard - brackets






9. Vertical line






10. No solution






11. [2x+3]=9 - [2x+3]=-9 write it both ways






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






13. Plug in vertices in objective function






14. A=b - then b=a






15. Function whose graph is a line






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






17. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






19. Same slopes






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






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






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






23. Slope of 1/1 - through 0






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






25. Opposite - reciprocal slopes






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






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






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






29. A=a it is what it is






30. 'Points' from side to side






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






32. 'Points' from BOTTOM to TOP






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






34. ROW x COLUMN






35. A=b - then ac=bc






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






37. Solve using every equation (use linear combination)


38. Horizontal line






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






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






41. One or more solutions






42. Shaded area






43. Soft - parentheses






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






45. Dotted line






46. x-value because its value is given






47. Shading goes down - or left






48. No fraction or decimal






49. 1 -2 -3...maybe 0






50. Substitute AND simplify
