Answer with explanation:
≡This plane is Called→ Two Dimensional Coordinate plane or x y plane.And the given statement is true Statement.
The Plane has two axes as a frame of reference. The x-axis is a horizontal line and the y-axis is perpendicular to it (i.e., the y-axis is vertical). The intersection of the two axes is called the origin.
⇒The value of x lies from (-∞,∞) .x∈[-∞,∞]
And ⇒,the value of y lies from (-∞,∞).y∈[-∞,∞]
And the points in this plane is represented in terms of Ordered pairs that is in the form of , (x,y).
→There are four Quadrants , in this plane and description of points is as follows:
In First Quadrant , both ,x and y positive.
In Second Quadrant ,x negative, and y positive.
In Third Quadrant ,x negative and y Negative.
In Fourth Quadrant ,x positive and y Negative.
