What is the formula for the equation of a tangent line?
What is the tangent line equation? The equation of the tangent line can be found using the formula y – y1 = m (x – x1), where m is the slope and (x1, y1) is the coordinate points of the line.
How do you find the tangent line of a parabola without calculus?
Suppose we want to find the slope of the tangent line to the parabola y = x^2 at any point \left(a, a^2\right). The line with slope m through this point is y – a^2 = m(x – a); intersecting this with the parabola by substituting, we have x^2 – a^2 = m(x – a). This simplifies to x^2 – mx + \left(ma – a^2\right) = 0.
