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=a it is what it is






2. Opposite - reciprocal slopes






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






4. 'Points' from side to side






5. [2x+3]=9 - [2x+3]=-9 write it both ways






6. No solution






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






8. Slope of 1/1 - through 0






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






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






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






12. Soft - parentheses






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






14. Shading goes up - or right






15. Function whose graph is a line






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






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






18. Same slopes






19. No fraction or decimal






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






21. Substitute AND simplify






22. Shading goes down - or left






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






24. mx+b=y






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






26. Set of ordered pairs (input and output)






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






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






29. x-value because its value is given






30. Horizontal line






31. Shaded area






32. 'Points' from BOTTOM to TOP






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






34. Dotted line






35. e.g x






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






37. Solid line






38. 1 -2 -3...maybe 0






39. Solve using every equation (use linear combination)


40. Vertical line






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






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






43. A=b - then b=a






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






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






46. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






47. Whats worth






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






49. A=b - then ac=bc






50. ROW x COLUMN
