Tangent, Curvature, Slope, Derivative

Tangent, in geometry, the tangent line to a curve at a point is that straight line that best approximates (or “clings to”) the curve near that point. It may be considered the limiting position of straight lines passing through the given point and a nearby point of the curve as the second point

Why do we take the derivative as the slope of the tangent line? It's just a point there and the point doesn't have a slope. Why do they say the secant eventually
