The equation of the curve is $\"\"$ .

Equation of the tangent line at point $\"\"$ is $\"\"$ .

The point $\"\"$ lies on the both tangent line and curve. \ \

Substitute $\"\"$ in the tangent line equation. \ \

$\"\"$ . \ \

\ \

Slope of the tangent line to the curve $\"\"$ at $\"\"$ is $\"\"$ . \ \

Here slope of the line is $\"\"$ . \ \

Slope intercept form of the equation is $\"\"$ .

Where $\"\"$ is slope of the line,

$\"\"$ is $\"\"$ - intercept.

Compare the tangent line $\"\"$ with $\"\"$ . \ \

Slope of the tangent line $\"\"$ at $\"\"$ is $\"\"$ . \ \
