Solution :

`x^2+y^2-2ax=0`<br>
`x+2y=0`<br>
equation of line<br>
x+2y++c=0<br>
a+0+c=0<br>
c=-a<br>
We get,<br>
x+2y-a=0<br>
From diagram<br>
`h=|(-a/sqrt5)`<br>
`h=a/sqrt5`<br>
b=2a<br>
area of triangle=`1/2*B*H`<br>
=`1/2*a/sqrt5*2a`<br>
=`a^2/sqrt5`**Theorem :-Every first degree equation in x,y represents a straight line.**

**Find the slope of a line when two points having coordinates are given ?**

**Find the slope of a line having equation of the form `ax+by+c=0`**

**Find the angles between two lines .**

**Examples :(i) Let A(6,4) and B(2,12) be two given points.Find the slope of the line perpendicular to AB. (ii) If line `3x-ay-1=0` is parallel to the line `(a-2)x-y+3=0` then find the values of a.**

**Condition for the parallelism of two lines.**

**Condition for Perpendicularity of two lines .**

**What is the intercept of a line on x- axis and y-axis ?**

**Equation of line parallel to x and y axis**

**Slope-intercept form of a line**
