Express the following linear equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case : $y-2=0$
Draw the graph and linear equations in two variables : $x + y = 4$
Check the solutions of the equation $x -2y = 4$ and which are not : $(\sqrt{2},\, 4 \sqrt{2})$
Find two solutions for each of the following equations :
$(i)$ $4 x+3 y=12$
$(ii)$ $2 x+5 y=0$
$(iii)$ $3 y+4=0$
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.
