In which quadrant does a point lie if its coordinates have opposite signs?

State whether the following statement is true or false:
The coordinate axes divide the Cartesian plane into four parts.

In the Cartesian plane,the vertical line passing through the origin is called the.......

The point $(0, -7)$ lies:

If $a=5, b=3, c=-8$ and $d=-5$,then in which quadrant does the point $(a+c, b+d)$ lie?

Plot the points $A(1, -1)$ and $B(4, 5)$.
$(i)$ Draw a line segment joining these points. Write the coordinates of a point on this line segment between the points $A$ and $B$.
$(ii)$ Extend this line segment and write the coordinates of a point on this line which lies outside the line segment $AB$.
