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






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






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






4. One or more solutions






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






6. Solid line






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






8. Function whose graph is a line






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






10. 1 -2 -3...maybe 0






11. Put is simplest form






12. mx+b=y






13. Soft - parentheses






14. 'Points' from side to side






15. A=a it is what it is






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






17. Opposite - reciprocal slopes






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






19. Shading goes down - or left






20. No solution






21. Same slopes






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






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






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






25. Horizontal line






26. Hard - brackets






27. ROW x COLUMN






28. A=b - then b=a






29. Vertical line






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






31. No fraction or decimal






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






33. x-value because its value is given






34. Intersecting points






35. A=b - then ac=bc






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






37. Shading goes up - or right






38. Solve using every equation (use linear combination)






39. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






40. Dotted line






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






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






43. e.g x






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






45. Plug in vertices in objective function






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






47. Set of ordered pairs (input and output)






48. Substitute AND simplify






49. Whats worth






50. Slope of 1/1 - through 0
