  1. 3. pairs of mathematical manipulations in which one operation undoes the action of the other. So the inverse of 3/4 is -4/3
  2. 7. form for linear equations. Ax+by=C
  3. 9. the multiples of a number. for example, 80 is 8x10 then 5x2 and 4x2
  4. 11. the smallest factor all the numbers share
  5. 13. used to find the slope and the intercept. the formula is y=mx+b
  6. 14. the shape on a graph moves up down left or right. Every one of the points moves in the same direction
  7. 17. the steepness of a line. Or rise/run
  8. 19. a numerical quantity that is not a whole number. Or could be recognized as division of two numbers
  9. 20. the power to a number. to the top right of a number 6^2
  10. 21. The shape on a graph rotates 90, 180, 270 degrees. clockwise or counter clockwise

  1. 1. (x2-x1)^2 + (y2-y1)^2 all of that is squared.
  2. 2. (x1+x2/2), (y1+y2/2)
  3. 4. the largest factor all the numbers share
  4. 5. indicate how many times one number contains another. So for example there are 8 boys and 6 girls. There is a 8:6 ______
  5. 6. how many times a number is being multiplied by it self.
  6. 8. when a shape is in the appearance like its in a mirror. Over the x or y axis
  7. 10. formula to find the slope and points on a graph. y-y1=m(x-x1)
  8. 12. the longest line on the triangle. The "C" on the triangle
  9. 15. an ordered list of numbers . The three dots mean to continue forward in the pattern established. Each number in the sequence is called a term.
  10. 16. theorem A^2+B^2=C
  11. 18. by a specified amount in or for every hundred. For example: 93/100
