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






2. Shading goes down - or left

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






18. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






21. 1 -2 -3...maybe 0






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






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






24. Function whose graph is a line






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






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






27. Plug in vertices in objective function






28. No fraction or decimal






29. Opposite - reciprocal slopes






30. Set of ordered pairs (input and output)






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






32. 'Points' from BOTTOM to TOP






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






34. ROW x COLUMN






35. Shaded area






36. Soft - parentheses






37. Solid line






38. A=b - then ac=bc






39. Same slopes






40. Intersecting points






41. Substitute AND simplify






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






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






44. x-value because its value is given






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