- 3. pairs of mathematical manipulations in which one operation undoes the action of the other. So the inverse of 3/4 is -4/3
- 7. form for linear equations. Ax+by=C
- 9. the multiples of a number. for example, 80 is 8x10 then 5x2 and 4x2
- 11. the smallest factor all the numbers share
- 13. used to find the slope and the intercept. the formula is y=mx+b
- 14. the shape on a graph moves up down left or right. Every one of the points moves in the same direction
- 17. the steepness of a line. Or rise/run
- 19. a numerical quantity that is not a whole number. Or could be recognized as division of two numbers
- 20. the power to a number. to the top right of a number 6^2
- 21. The shape on a graph rotates 90, 180, 270 degrees. clockwise or counter clockwise
Down
- 1. (x2-x1)^2 + (y2-y1)^2 all of that is squared.
- 2. (x1+x2/2), (y1+y2/2)
- 4. the largest factor all the numbers share
- 5. indicate how many times one number contains another. So for example there are 8 boys and 6 girls. There is a 8:6 ______
- 6. how many times a number is being multiplied by it self.
- 8. when a shape is in the appearance like its in a mirror. Over the x or y axis
- 10. formula to find the slope and points on a graph. y-y1=m(x-x1)
- 12. the longest line on the triangle. The "C" on the triangle
- 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.
- 16. theorem A^2+B^2=C
- 18. by a specified amount in or for every hundred. For example: 93/100
