Question

What is meant by positive direction of x axis or y axis given in question.

Answer 1

Hint: A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the \[x - axis\]. The vertical axis is called the \[y - axis.\] The point where the \[x - axis\] and \[y - axis.\]intersect is called the origin. A coordinate grid has two perpendicular lines or axes labeled like number lines. The horizontal axis is called\[x - axis\]. The point where \[x - axis\]and \[y - axis.\]intersect is called origin.
The horizontal axis is called the x-axis and the vertical one is the y-axis.
The coordinate is often denoting by the letters \[x,{\text{ }}y\]and z or \[x,{\text{ }}y,{\text{ }}z.\]The axis may then be referred to as the\[x - axis\], \[y - axis\]and \[z - axis.\].

Complete step-by-step solution:
The coordinates are divided into four quadrants as shown in the diagram, the \[ + ve\] direction of x-axis or y-axis means the \[ + ve\] value of the x, y coordinates.

 

Note:
The horizontal line to the right of the origin is called the \[ + ve\] axis and the horizontal line to the left of the origin is called \[ - ve\] \[x - axis.\]
The vertical lines above the origin are called \[ + ve\] \[y - axis.\]and the vertical lines below the origin are called \[ - ve\] \[y - axis.\]
All points of the plane can be identically uniquely by their x and y coordinates.
