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. Horizontal line






2. One or more solutions






3. Whats worth






4. Slope of 1/1 - through 0






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






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






7. ROW x COLUMN






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






9. Hard - brackets






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






11. Function whose graph is a line






12. Shading goes up - or right






13. Substitute AND simplify






14. Solve using every equation (use linear combination)






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






16. mx+b=y






17. Solid line






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






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






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






21. Soft - parentheses






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






23. No solution






24. A=b - then b=a






25. A=a it is what it is






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






27. Same slopes






28. 1 -2 -3...maybe 0






29. Intersecting points






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






31. Shading goes down - or left






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






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






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






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






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






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






38. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






39. [2x+3]=9 - [2x+3]=-9 write it both ways






40. Shaded area






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






42. Plug in vertices in objective function






43. Put is simplest form






44. 'Points' from side to side






45. x-value because its value is given






46. A=b - then ac=bc






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






48. 'Points' from BOTTOM to TOP






49. No fraction or decimal






50. Dotted line
