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. Shaded area






2. Opposite - reciprocal slopes






3. Hard - brackets






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






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






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






7. Whats worth






8. Slope of 1/1 - through 0






9. Substitute AND simplify






10. 'Points' from BOTTOM to TOP






11. ROW x COLUMN






12. Vertical line






13. Function whose graph is a line






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






15. 'Points' from side to side






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






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






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






19. Set of ordered pairs (input and output)






20. Shading goes down - or left






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






22. 1 -2 -3...maybe 0






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






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






25. Intersecting points






26. Soft - parentheses






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






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






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






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






31. Dotted line






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






33. Solid line






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






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






36. Horizontal line






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






38. Same slopes






39. No fraction or decimal






40. A=b - then ac=bc






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






42. No solution






43. [2x+3]=9 - [2x+3]=-9 write it both ways






44. One or more solutions






45. Solve using every equation (use linear combination)

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






47. A=a it is what it is






48. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






49. e.g x






50. Shading goes up - or right
