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






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






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






4. Set of ordered pairs (input and output)






5. Solid line






6. x-value because its value is given






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






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






9. Shading goes down - or left






10. No fraction or decimal






11. Whats worth






12. ROW x COLUMN






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






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






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






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






17. Soft - parentheses






18. Function whose graph is a line






19. Hard - brackets






20. Same slopes






21. Slope of 1/1 - through 0






22. 1 -2 -3...maybe 0






23. A=a it is what it is






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






25. Intersecting points






26. e.g x






27. Shaded area






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






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






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






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






32. No solution






33. Horizontal line






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






35. Opposite - reciprocal slopes






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






37. 'Points' from BOTTOM to TOP






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






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






40. A=b - then b=a






41. Vertical line






42. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






43. Put is simplest form






44. mx+b=y






45. 'Points' from side to side






46. Substitute AND simplify






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






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






49. Dotted line






50. A=b - then ac=bc
