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






3. Hard - brackets






4. x-value because its value is given






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






6. Set of ordered pairs (input and output)






7. No fraction or decimal






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






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






10. Shading goes down - or left






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






12. Horizontal line






13. Shading goes up - or right






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






15. Soft - parentheses






16. Put is simplest form






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






18. 'Points' from side to side






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






20. A=b - then ac=bc






21. 1 -2 -3...maybe 0






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






23. Substitute AND simplify






24. Slope of 1/1 - through 0






25. ROW x COLUMN






26. Function whose graph is a line






27. Solid line






28. Shaded area






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






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






31. Solve using every equation (use linear combination)

32. Dotted line






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






34. 'Points' from BOTTOM to TOP






35. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






37. [2x+3]=9 - [2x+3]=-9 write it both ways






38. Opposite - reciprocal slopes






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






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






41. No solution






42. A=b - then b=a






43. A=a it is what it is






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






45. Same slopes






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






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






48. Vertical line






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






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