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






2. Substitute AND simplify






3. Horizontal line






4. Soft - parentheses






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






6. Put is simplest form






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






8. Shading goes up - or right






9. Vertical line






10. A=b - then b=a






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






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






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






14. Function whose graph is a line






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






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






17. A=b - then ac=bc






18. x-value because its value is given






19. Slope of 1/1 - through 0






20. 'Points' from side to side






21. A=a it is what it is






22. No fraction or decimal






23. 'Points' from BOTTOM to TOP






24. Opposite - reciprocal slopes






25. 1 -2 -3...maybe 0






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






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






28. Dotted line






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






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






31. Shading goes down - or left






32. Shaded area






33. mx+b=y






34. Solve using every equation (use linear combination)

38. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






40. [2x+3]=9 - [2x+3]=-9 write it both ways






41. Intersecting points






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. Hard - brackets






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






45. One or more solutions






46. Solid line






47. e.g x






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