Step-by-step explanation:
From the given figure, it can be seen that the coordinates of the given points are:
[tex]A=(0,0),B=(2a,0),A=(0,2b),P=(a,0),Q=(a,b),R=(0,b)[/tex]
Now, The coordinates of P, Q and R are:
[tex]\begin{gathered} P=(a,0) \\ Q=(a,b) \\ R=(0,b) \end{gathered}[/tex]
Now, slope of PQ is given as:
[tex]S=\frac{b-0}{a-a}=\frac{b}{0}[/tex]
which is undefined.
Slope of RQ is given as:
[tex]S=\frac{b-b}{a-0}=\frac{0}{a}=0[/tex]
which are the required slope of PQ and RQ respectively.
