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. Shading goes up - or right






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






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






4. Put is simplest form






5. Slope of 1/1 - through 0






6. Solve using every equation (use linear combination)

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






8. No solution






9. Dotted line






10. Substitute AND simplify






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






12. Soft - parentheses






13. Solid line






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






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






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






17. A=b - then b=a






18. Shading goes down - or left






19. A=a it is what it is






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






21. Hard - brackets






22. Whats worth






23. 'Points' from BOTTOM to TOP






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






25. Set of ordered pairs (input and output)






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






27. A=b - then ac=bc






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






29. No fraction or decimal






30. mx+b=y






31. Function whose graph is a line






32. ROW x COLUMN






33. Vertical line






34. e.g x






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






36. Opposite - reciprocal slopes






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






38. x-value because its value is given






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






40. 'Points' from side to side






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






42. Intersecting points






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






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






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






46. Same slopes






47. Plug in vertices in objective function






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






49. Shaded area






50. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3
