Check whether $(0, 2)$ is a solution of the equation $x - 2y = 4$.

From the choices given below,choose the equation whose graphs are given in Fig. $(i)$ and Fig. $(ii)$.
For Fig. $(i)$:
$(a)$ $y=x$
$(b)$ $x+y=0$
$(c)$ $y=2x$
$(d)$ $2+3y=7x$
For Fig. $(ii)$:
$(a)$ $y=x+2$
$(b)$ $y=x-2$
$(c)$ $y=-x+2$
$(d)$ $x+2y=6$

Yamini and Fatima,two students of Class $IX$ of a school,together contributed Rs. $100$ towards the Prime Minister's Relief Fund to help the earthquake victims. Write a linear equation which satisfies this data. (You may take their contributions as Rs. $x$ and Rs. $y$.) Draw the graph of the same.

Give the geometric representations of $2x + 9 = 0$ as an equation
$(i)$ in one variable
$(ii)$ in two variables

Find two solutions for each of the following equations:
