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. Opposite - reciprocal slopes






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






3. ROW x COLUMN






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






5. Substitute AND simplify






6. Hard - brackets






7. One or more solutions






8. 'Points' from side to side






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






10. 1 -2 -3...maybe 0






11. A=a it is what it is






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






13. Shading goes down - or left






14. Set of ordered pairs (input and output)






15. Same slopes






16. No solution






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






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






19. e.g x






20. No fraction or decimal






21. Intersecting points






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






23. Put is simplest form






24. Solid line






25. Function whose graph is a line






26. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






27. Shaded area






28. Solve using every equation (use linear combination)


29. Rectangular array of #s written w/brackets (classified by # of numbers in row and column e.g. 3x3)






30. Whats worth






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






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






33. Horizontal line






34. A=b - then ac=bc






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






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






37. Plug in vertices in objective function






38. x-value because its value is given






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






40. Dotted line






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






42. Vertical line






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






44. Slope of 1/1 - through 0






45. A=b - then b=a






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






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






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






49. Soft - parentheses






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