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. mx+b=y






2. Vertical line






3. Put is simplest form






4. [2x+3]=9 - [2x+3]=-9 write it both ways






5. Function whose graph is a line






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






7. Dotted line






8. Whats worth






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






10. A=b - then ac=bc






11. Horizontal line






12. Soft - parentheses






13. 'Points' from BOTTOM to TOP






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






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






16. Same slopes






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






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






19. Plug in vertices in objective function






20. Solid line






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






22. x-value because its value is given






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






24. 'Points' from side to side






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






26. Opposite - reciprocal slopes






27. Shading goes down - or left






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






29. Set of ordered pairs (input and output)






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






31. 1 -2 -3...maybe 0






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






33. ROW x COLUMN






34. Shading goes up - or right






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






36. Substitute AND simplify






37. Shaded area






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






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






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






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






42. A=a it is what it is






43. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






44. A=b - then b=a






45. Hard - brackets






46. No solution






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






48. Slope of 1/1 - through 0






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






50. e.g x
