Scene 1

} A  coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis . This formula is used to find the coordinates at which a line is divided into two equal halves

origin. } The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.. 

Scene 2

} The  point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the  y-axis.

}The two intersecting lines in the Cartesian plane make four distinct graph quadrants. This x-axis and y-axis of a graph divide it into four quadrants. Moreover, each quadrant includes a combination of positive and negative values for coordinates x and y.

Signs of coordinates of points in different quadrants: Quadrant  1 : (+x, +y) Quadrant  2 : (-x, +y) Quadrant  3 : (-x, -y) Quadrant  4 : (+x, -y)

ABSCISSA & ORDINATE. }Abscissa is the distance from a point to the vertical or y -axis, measured parallel to the horizontal or x -axis. It is also known as the x -coordinate. } Ordinate is the distance from a point to the horizontal or x -axis, measured parallel to the vertical or y -axis. It is also known as the y -coordinate .. 

Scene 3

}Abscissa  is the distance from a point to the vertical or y -axis, measured parallel to the horizontal or x -axis. It is also known as the x -coordinate.  } Ordinate  is the distance from a point to the horizontal or x -axis, measured parallel to the vertical or y -axis. It is also known as the y -coordinate .

Introduction to Slope of a Line | The slope of line is the measure of steepness or the direction of line the coordinate plane.

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is  Δy , while the net change in the x coordinate is  Δx . So the change in y coordinate with respect to the change in x coordinate can be written as ,   m =  Δy / Δx where, m  is the slope Note that tan θ =  Δy / Δx We also refer this tan θ to be the slope of the  line. See in figure..
