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. A=b - then ac=bc






3. Intersecting points






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






5. x-value because its value is given






6. Shading goes down - or left






7. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






8. 'Points' from BOTTOM to TOP






9. Shaded area






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






11. Whats worth






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






13. Soft - parentheses






14. No solution






15. e.g x






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






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






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






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






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






21. Same slopes






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






23. Horizontal line






24. Function whose graph is a line






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






26. Substitute AND simplify






27. Solve using every equation (use linear combination)

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






29. A=a it is what it is






30. Dotted line






31. No fraction or decimal






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






33. A=b - then b=a






34. 1 -2 -3...maybe 0






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






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






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






38. Put is simplest form






39. One or more solutions






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






41. Vertical line






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






43. Shading goes up - or right






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






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






46. Opposite - reciprocal slopes






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






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






49. Slope of 1/1 - through 0






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