Final answer:
To find the equation of the tangent line to a curve at a given point, use the point-slope form of a line.
Step-by-step explanation:
To find the equation of the tangent line to a curve at a given point, you can use the point-slope form of a line. First, find the slope of the curve at the given point using implicit differentiation or other methods. Then, use the coordinates of the point and the slope to write the equation of the tangent line in the point-slope form.
