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. 'Points' from side to side






2. No solution






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






4. Intersecting points






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






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






7. [2x+3]=9 - [2x+3]=-9 write it both ways






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






9. Dotted line






10. Function whose graph is a line






11. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






12. Slope of 1/1 - through 0






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






14. One or more solutions






15. e.g x






16. Shading goes down - or left






17. Same slopes






18. 'Points' from BOTTOM to TOP






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






20. Substitute AND simplify






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






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






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






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






25. Whats worth






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






27. Opposite - reciprocal slopes






28. Plug in vertices in objective function






29. Soft - parentheses






30. Solid line






31. ROW x COLUMN






32. A=b - then b=a






33. Set of ordered pairs (input and output)






34. A=a it is what it is






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






36. No fraction or decimal






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






38. Shaded area






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






40. Horizontal line






41. 1 -2 -3...maybe 0






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






43. Vertical line






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






45. mx+b=y






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






47. Hard - brackets






48. x-value because its value is given






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






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