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






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






3. 'Points' from BOTTOM to TOP






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






5. Function whose graph is a line






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






7. Set of ordered pairs (input and output)






8. Solid line






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






10. Intersecting points






11. Substitute AND simplify






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






13. Slope of 1/1 - through 0






14. 1 -2 -3...maybe 0






15. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






16. Hard - brackets






17. mx+b=y






18. Put is simplest form






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






20. No fraction or decimal






21. x-value because its value is given






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






23. One or more solutions






24. Shaded area






25. No solution






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






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






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






29. A=a it is what it is






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






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






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






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






34. Whats worth






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






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






37. [2x+3]=9 - [2x+3]=-9 write it both ways






38. Shading goes down - or left






39. Vertical line






40. ROW x COLUMN






41. A=b - then ac=bc






42. Plug in vertices in objective function






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






44. 'Points' from side to side






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






46. Dotted line






47. Opposite - reciprocal slopes






48. A=b - then b=a






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






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