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






2. Plug in vertices in objective function






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






4. Shaded area






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






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






7. Put is simplest form






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






9. Function whose graph is a line






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






11. A=a it is what it is






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






13. One or more solutions






14. Soft - parentheses






15. x-value because its value is given






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






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






18. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






19. [2x+3]=9 - [2x+3]=-9 write it both ways






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






21. Whats worth






22. Substitute AND simplify






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






24. Same slopes






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






26. e.g x






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






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






29. A=b - then ac=bc






30. Vertical line






31. Horizontal line






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






33. Solid line






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






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






36. Intersecting points






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






38. Shading goes down - or left






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






40. 'Points' from BOTTOM to TOP






41. mx+b=y






42. Dotted line






43. Shading goes up - or right






44. Slope of 1/1 - through 0






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






46. ROW x COLUMN






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






48. 'Points' from side to side






49. No solution






50. A=b - then b=a
