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. A=b - then b=a






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






3. Solid line






4. Solve using every equation (use linear combination)


5. Dotted line






6. Horizontal line






7. Soft - parentheses






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






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






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






11. Hard - brackets






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






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






14. Set of ordered pairs (input and output)






15. Slope of 1/1 - through 0






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






17. Substitute AND simplify






18. 'Points' from BOTTOM to TOP






19. Shading goes down - or left






20. No fraction or decimal






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






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






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






24. Opposite - reciprocal slopes






25. Same slopes






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






27. Shading goes up - or right






28. ROW x COLUMN






29. mx+b=y






30. x-value because its value is given






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






32. e.g x






33. [2x+3]=9 - [2x+3]=-9 write it both ways






34. A=b - then ac=bc






35. Plug in vertices in objective function






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






37. Put is simplest form






38. Vertical line






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






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






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






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






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






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






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






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






47. Function whose graph is a line






48. No solution






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






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