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






2. Same slopes






3. Hard - brackets






4. Shaded area






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






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






7. A=b - then b=a






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






9. Vertical line






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






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






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






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






14. A=b - then ac=bc






15. Shading goes up - or right






16. Whats worth






17. x-value because its value is given






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






19. No fraction or decimal






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






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






22. Solve using every equation (use linear combination)

23. One or more solutions






24. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






25. Plug in vertices in objective function






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






27. Opposite - reciprocal slopes






28. Dotted line






29. Put is simplest form






30. Soft - parentheses






31. e.g x






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






33. Set of ordered pairs (input and output)






34. No solution






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






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






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






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






39. ROW x COLUMN






40. Solid line






41. Slope of 1/1 - through 0






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






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






44. [2x+3]=9 - [2x+3]=-9 write it both ways






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






46. A=a it is what it is






47. 'Points' from side to side






48. Horizontal line






49. Substitute AND simplify






50. Function whose graph is a line
