Answer:
Horizontal number line is the x axis and the vertical line is the y axis.
The part of x axis towards right of origin is the positive x axis and the one towards left of origin is the negative x axis.
which is similarly the part of y axis above the origin, is the positive y axis and the part of y axis below the origin, is the negative y axis.
So then every point in the coordinate plane is represented by an ordered pair of x and y coordinates.
