The derivative is
The slope of the tangent line at the point (-1, 2) is the value of the derivative at x = -1.
The slope of the normal line is the opposite reciprocal of the slope of the tangent line.
Using the Point-Slope form of a linear equation, the normal line is
Answer:
Step-by-step explanation:
<em>Replace it with y</em>
<em>Exchange the values of x and y</em>
<em>Solve for y</em>
<em>Subtracting 1 from both sides</em>
<em>Dividing both sides by 2</em>
<em>Replace it by </em>
So,
