Solve, graphically, the pairs of equations:

$$\begin{gathered} 3x+7y=27 \\ 8-y=\frac{5}{2}x \end{gathered}$$

Solve, graphically, the pairs of equations:

$\frac{x+1}{4}=\frac{2}{3}\left(1-2y\right)$

$\frac{2+5y}{3}=\frac{x}{7}-2$

Solve graphically the simultaneous equations given below. Take the scale as $2 \mathrm{cm} = 1$ unit on both the axes.

$x-2y-4=0$

$2x + y = 3$

Use graph paper for this question. Draw the graph of $2x-y- 1 = 0$ and $2x + y = 9$ on the same axes. Use $2\mathrm{cm}= 1$ unit on both axes and plot only $3$ points per line. Write down the co-ordinates of the point of intersection of the two lines.

Use graph paper for this question. Take $2 \mathrm{cm} = 2$ units on x-axis and $2 \mathrm{cm} = 1$ unit on y-axis: Solve graphically the following equations

$3x + 5y = 12 ; 3x - 5y + 18 = 0$ (Plot only three points per line)

Use graph paper for this question. 

Draw the graph of $x+y+3=0$ and $3x-2y+4=0$. Plot only three points per line.

Use graph paper for this question. Take $2 \mathrm{cm}=1 \mathrm{unit}$ on both axes.

Write down the coordinates of the point of intersection of the lines: $x+y+3=0$ and $3x-2y+4=0$

Use graph paper for this question. Take $2 \mathrm{cm}=1 \mathrm{unit}$ on both axes.

Measure and record the distance of the point of intersection of the lines from the origin in cm.

The sides of a triangle are given by the equations $y-2=0, y + 1 = 3(x - 2)$ and $x + 2y = 0$. Find the area of triangle(graphically).
