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






2. Solid line






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






4. A=b - then b=a






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






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






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






8. 'Points' from side to side






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






10. Hard - brackets






11. Same slopes






12. e.g x






13. ROW x COLUMN






14. Intersecting points






15. x-value because its value is given






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






17. Plug in vertices in objective function






18. No solution






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






20. No fraction or decimal






21. One or more solutions






22. Whats worth






23. Put is simplest form






24. Opposite - reciprocal slopes






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






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






27. 1 -2 -3...maybe 0






28. Solve using every equation (use linear combination)

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






40. Shaded area






41. Vertical line






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






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






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






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






46. Dotted line






47. Slope of 1/1 - through 0
