Give the geometric representation of $2x+9=0$ as an equation in two variables.

Express the following equation as linear equation in two variables in the standard form and indicate the values of $a.b$ and $c$ in given case. 

$\frac{\sqrt{3}}{2}y=3$

Solve for $x$.

$\frac{3x+2}{7}+\frac{4(x+1)}{5}=\frac{2}{3}(2x+1)$

Write the following equation in the form $ax+by+c=0$ and indicate the value of $a,b$ and $c$ in the given case.

$x+y=-2$

Write the following equation in the form $ax+by+c=0$ and indicate the value of $a,b$ and $c$ in given case.

$2x+3y+5=3$

Write the following equation in the form $ax+by+c=0$ and indicate the value of $a,b$ and $c$ in given case.

$\frac{3}{2}y+\frac{x}{4}=\frac{2}{3}$
