Are all straight lines the same?

Straight lines are use to illustrate the linear relationship between TWO variables / unknowns.

We have also been creating straight lines using Geo-Gebra.

How do we differentiate one straight line from another?

What are some of the properties that will cause one straight line to be different from another.

  1. Names: a or b, like Algebra, used automatically in Geogebra

    Two points: The 2 points the lines are connected to. (e.g. AB)

  2. we can differentiate them from the dots hat they are joined to

    the angle of the point, that they are joined.

  3. the dots that are joined by the line, like a and b line.

  4. You would have to see the points at which the line connect, and the directions and grid squares which the line traverses.

  6. The gradient of each line is different. This is because the points which are linked are different.

  7. How do we differentiate one straight line from another?

    -We can differentiate one line from another by the dots that they connect to.
    -We can differentiate one line from another by the starting coordinate to the ending coordinate.

    What are some of the properties that will cause one straight line to be different from another.

    -The dots that are connected to the individual straight lines.

  8. We can differentiate them by the dots they are connected to, and the angle of the line in which it is connected to the dots by.

  9. We can differentiate one straight line from another by the different points they are linked to. The name of the line is created by the name of the first dot it is linked to and the second dot it is linked to. For example, one straight line is created by connecting Point A and Point B together, the name of the line will be AB. This is how we differentiate the lines.

  10. The points that the lines cut through have different names and the angle of the lines are different.

  11. The dots that they are joined to can differentiate them. one line would not be joined to 3 dots at a time. two consecutive letters make one line. Also, the lines are joined mostly in different directions.

  12. The dots are named, thus the lines can be differentiated that way. The lines can be differentiated using the coordinates that are given on the side of geogebra

  13. The 'angle' of each line is different. The dots are at different coordinates.

  14. 1) We can differentiate by labeling them. Like a,b,c,d,e,f,g...

    2) Some properties are: the line is connected to different points, and the points also have names, so it makes each line different.

    I Have A Feeling That This Makes No Sense.

  15. Names of the lines like: X, Y. Similar to Algebra.

    The two points that the lines are connected to.

  16. The letters marking the ends of the lines will tell that the lines are different.

  17. Names the dots/lines like A, B, C or D...

  18. the points that they past through or are connected to e.g line AB/BC

  19. We can differentiate one line from another by the dots that they connect to.

    The dots that are connected to the individual straight lines.

  20. The alphabet at the end of each line can help us differentiate because each line has a different alphabet.

  21. We differentiate one straight line from another by seeing if the line is connected to a point, if there is no other line connected to the point that the line is connected to, we can differentiate that line from other lines
