The equation is $\"\"$ .

The slope intercept form of line equation is $\"\"$ .

Where $\"\"$ is the slope of the line and $\"\"$ is the $\"\"$ intercept of the line equation.

Compare the line equation with slope intercept form of line equation.

Therefore, the slope of line equation is $\"\"$ .

The line passing through the two points $\"\"$ and $\"\"$ .

Slope of the line passing through the points $\"\"$ and $\"\"$ is $\"\"$ .

The slope of the line passing through the points $\"\"$ and $\"\"$ is $\"\"$ .

$\"\"$

The line passing through the points $\"\"$ and $\"\"$ is perpendicular to the line $\"\"$ .

If the two lines are perpendicular then their slopes are negative reciprocals to each other i.e

\"\"

\"\"

Therefore, the value of

\"\"
