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. Shading goes up - or right






2. mx+b=y






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






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






5. No solution






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






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






8. Shaded area






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






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






11. Horizontal line






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






13. Plug in vertices in objective function






14. x-value because its value is given






15. Opposite - reciprocal slopes






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






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






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






19. Substitute AND simplify






20. Function whose graph is a line






21. Put is simplest form






22. No fraction or decimal






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






24. Dotted line






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






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






27. Slope of 1/1 - through 0






28. [2x+3]=9 - [2x+3]=-9 write it both ways






29. A=a it is what it is






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






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






32. A=b - then b=a






33. 1 -2 -3...maybe 0






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






35. One or more solutions






36. Solid line






37. Hard - brackets






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






39. A=b - then ac=bc






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






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






42. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






43. Set of ordered pairs (input and output)






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






45. 'Points' from side to side






46. Shading goes down - or left






47. Whats worth






48. e.g x






49. Intersecting points






50. ROW x COLUMN
