R K Bansal Solutions for Exercise 1: EXERCISE

The graph of $3x+2y=6$ meets the $x-$axis at point $P$ and the $y-$axis at point $Q$. Use the graphical method to find the co-ordinates of points $P$ and $Q$.

Draw the graphs of equation $x+2y-3=0$. From the graph find: $x_1$, the value of $x$, when $y=3$

Draw the graphs of equation $x+2y-3=0$. From the graph find: $x_2$, the value of $x$, when $y=-2$

Draw the graphs of equation $3x-4y=12$. From the graph find the value of $y$, when $x=-4$

Draw the graphs of equation $3x-4y=12$. From the graph find: $y_2$, the value of $y$, when $x=0$

Draw the graphs of equation $\frac{x}{4}+\frac{y}{5}=1$. From the graph find: $x_1$, the value of $x$, when $y=10$

Draw the graphs of equation $\frac{x}{4}+\frac{y}{5}=1$. From the graph find: $y_1$, the value of $y$, when $x=8$

Use the graphical method to show that the straight lines given by the equations $x+y=2, x-2y=5$ and $\frac{x}{3}+y=0$ pass through the same point.
