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 whose graph is a line






2. Set of ordered pairs (input and output)






3. Substitute AND simplify






4. Shading goes up - or right






5. A=a it is what it is






6. Hard - brackets






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






8. Intersecting points






9. Same slopes






10. Plug in vertices in objective function






11. One or more solutions






12. Put is simplest form






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






14. Opposite - reciprocal slopes






15. [2x+3]=9 - [2x+3]=-9 write it both ways






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






17. Whats worth






18. Soft - parentheses






19. Vertical line






20. Shading goes down - or left






21. Dotted line






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






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

33. Solid line






34. 'Points' from side to side






35. A=b - then ac=bc






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






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






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






39. A=b - then b=a






40. No solution






41. e.g x






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

47. Horizontal line






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






49. No fraction or decimal






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