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. Slope of 1/1 - through 0






2. mx+b=y






3. Vertical line






4. A=a it is what it is






5. Put is simplest form






6. Shading goes down - or left






7. Opposite - reciprocal slopes






8. A=b - then ac=bc






9. 1 -2 -3...maybe 0






10. Soft - parentheses






11. Dotted line






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






13. x-value because its value is given






14. A=b - then b=a






15. No fraction or decimal






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






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






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






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






20. Set of ordered pairs (input and output)






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






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






23. Solve using every equation (use linear combination)


24. Shading goes up - or right






25. Substitute AND simplify






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






27. Horizontal line






28. Hard - brackets






29. One or more solutions






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






31. No solution






32. Function whose graph is a line






33. ROW x COLUMN






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






35. 'Points' from BOTTOM to TOP






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






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






38. Whats worth






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






40. Solid line






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






42. [2x+3]=9 - [2x+3]=-9 write it both ways






43. 'Points' from side to side






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






45. Intersecting points






46. e.g x






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






48. Plug in vertices in objective function






49. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






50. Same slopes
