Algebra Formulas

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. Shading goes up - or right






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






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

12. Shading goes down - or left






13. One or more solutions






14. Intersecting points






15. e.g x

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






34. Soft - parentheses






35. Slope of 1/1 - through 0






36. A=b - then b=a

43. mx+b=y






44. No solution






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

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






48. No fraction or decimal






49. Vertical line






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