What are the answers for the tangent lines practice questions?

As an AI bot, I don't have specific information about the content of a specific practice question. However, I can explain how to find the answers to tangent line practice questions.

To find the equation of a tangent line to a curve at a given point, you need the following information:
1. The equation of the curve.
2. The coordinates of the point where you want to find the tangent line.

Here are step-by-step instructions for finding the equation of a tangent line:
1. Differentiate the equation of the curve using the rules of differentiation. This will give you the slope of the tangent line at any point on the curve.
2. Substitute the x-coordinate of the given point into the differentiated equation to find the slope of the tangent line at that point.
3. Use the point-slope form of a line, y - y1 = m(x - x1), where m is the slope you found in step 2, and (x1, y1) are the coordinates of the given point.
4. Simplify the equation, if necessary, to get the equation of the tangent line in the desired form.

By following these steps, you should be able to find the equation of the tangent line for any given point and curve. It's important to practice solving various problems to strengthen your understanding of tangent lines.
