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. Substitute AND simplify






2. Same slopes






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






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






5. Shaded area






6. Horizontal line






7. Put is simplest form






8. mx+b=y






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






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






11. Slope of 1/1 - through 0






12. A=a it is what it is






13. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






15. Solid line






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






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






18. Hard - brackets






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






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






21. Plug in vertices in objective function






22. Shading goes down - or left






23. [2x+3]=9 - [2x+3]=-9 write it both ways






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






25. Whats worth






26. Set of ordered pairs (input and output)






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






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






29. No solution






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






31. Dotted line






32. Opposite - reciprocal slopes






33. Function whose graph is a line






34. A=b - then ac=bc






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






36. A=b - then b=a






37. No fraction or decimal






38. e.g x






39. 'Points' from side to side






40. Intersecting points






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






42. Soft - parentheses






43. Solve using every equation (use linear combination)


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






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






46. 'Points' from BOTTOM to TOP






47. Vertical line






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






49. One or more solutions






50. Shading goes up - or right
