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 $$x,y$$and z or $$x,y,z.$$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.
