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. Correct result - but doesn't work in equation






2. Shading goes up - or right






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






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






5. Shaded area






6. Same slopes






7. Slope of 1/1 - through 0






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






9. Put is simplest form






10. Solve using every equation (use linear combination)

14. One or more solutions






15. Set of ordered pairs (input and output)






16. Intersecting points






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






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






19. 1 -2 -3...maybe 0






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






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

26. A=b - then ac=bc






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






28. ROW x COLUMN






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






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






31. x-value because its value is given






32. Opposite - reciprocal slopes






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






34. 'Points' from BOTTOM to TOP






35. Dotted line






36. No fraction or decimal






37. mx+b=y






38. A=b - then b=a






39. Vertical line






40. e.g x






41. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






42. Shading goes down - or left






43. Soft - parentheses

45. Hard - brackets






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






47. A=a it is what it is






48. Horizontal line






49. No solution






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