Fill in the blanks:(i)         The x–axis and y–axis taken together determine a plane known as____(ii)        The coordinates of points in the XY–plane are of the form_____(iii)       Coordinate planes divide the space into ____ octants____

Explanation

(i) The x-axis and y-axis taken together determine a plane known as XY-plane

(ii) The coordinates of points in the XY-plane are of the form `(x,y,0)`, where x is x-coordinate and y is y-coordinate

(iii) Coordinate planes divide the space into 8 octants.
