Final answer:
The equation of a tangent line can be found using different methods, such as the slope-intercept formula, point-slope form, tangent equation generator, and linear approximation method.
Step-by-step explanation:
The equation of a tangent line can be found using different methods. The slope-intercept formula is one way to find the equation of a tangent line. It uses the slope and y-intercept of the line. The point-slope form is another method that uses the slope and a point on the line to find the equation. A tangent equation generator is a tool that can generate the equation of a tangent line given a curve and a point. Lastly, the linear approximation method is a way to find an approximate equation of the tangent line using calculus.
