Linear Graphs 4 (Gradient)

Activity using TI-Nspire (in-class collaboration)
The table below shows some of the comments made by the class to show the various characteristics of the following gradient types:
.1 Positive
.2 Negative
.3 Zero
.4 Undefined

    The slope is sloping downwards from left to right
    The slope is sloping upwards from left to right
    A vertical line
    A horizontal line

  2. Negative Gradient: The slope is sloping downwards from the left to right.

    Positive gradient: The slope is sloping upwards from the left to right.

    Undefined Gradient: A vertical line which is parallel to the y-Axis.

    Zero Gradient: A horizontal line parallel to the x-axis.

    Negative gradient: The slope is sloping towards the right.
    Positive gradient: The slope is sloping towards the left.
    Undefined gradient: The slope is parallel to the y-axis. A vertical line.
    Zero gradient: The slope is parallel to the x-axis. A horizontal line.

  4. 1. Negative
    It will be negative when the line is connecting the 2nd to 4th quadrant.

    2. Positive
    It will be positive when the line is connecting the 1st to 3rd quadrant.

    3. Undefined
    The gradient wil be undefined when the slope is parallel with the y-axis

    4. Zero
    When the slope is parallel to the x-axis

    Negative Gradient: The slope is sloping downwards from left to right
    Positive Gradient:The slope is sloping upwards from left to right
    Undefined gradient: It is undefined when is parallel to the y-axis
    Zero Gradient: It is zero when it is parallel to the x-axis

  6. Negative gradient:
    It will be negative when the line slopes downwards from the left to the right.
    Positive gradient:
    It will be positive when the line slopes upwards from the left to the right.
    Undefined gradient.
    It will be undefined when the line is vertically parallel to the y-axis.
    Zero gradient:
    It will be zero when the line is horizontally straight and parallel to the x-axis, having no slope or bump at all.

  7. 1) It will be negative when the line is connecting the 2nd and 4th quadrant [May need to extend]

    2) It will be positive when the line is connecting the 1st and 3rd quadrant [May need to extend]

    3) When it is parallel to the y-axis

    4) When the line it is parallel to the x0axis

  8. Negative Gradient: It is when the slope is sloping downwards from left to right.
    Positive Gradient: It is when the slope is sloping upwards from left to right.
    Undefined Gradient: It is when the line is parallel to the y-axis.
    Zero Gradient: It is when the line is parallel to the x-axis.

  9. Negative Gradient: The gradient will be negative when the ending of the line is in the top left or bottom left of the beginning of the line
    Positive Gradient:

    Positive Gradient: It is positive when the slope slants towards the quadrant 3.

    Undefined Gradient: It is undefined when it is parallel to the y-axis and perpendicular to the x-axis and and it is a vertical line and it should be very steep.

    Zero Gradiant: The gradient is zero when the line is parallel to the x-axis and is perpendicular to the y-axis.
