How do you find the slope of a tangent line

WebMar 26, 2016 · Because the equation of the parabola is you can take a general point on the parabola, ( x, y) and substitute for y. Take the derivative of the parabola. Using the slope formula, set the slope of each tangent line from (1, –1) to equal to the derivative at which is 2 x, and solve for x. WebSince the tangent line is parallel to the line 2x - y = 1, the slopes are equal. slope of the tangent line = 2 The tangent line is passing through the point (2, -1) with the slope 2. Equation of the tangent line : y - y 1 = m (x - x 1) Substitute m = 2 and (x1, y1) = (2, -1). y + 1 = 2 (x - 2) y + 1 = 2x - 4 2x - y - 5 = 0 Example 5 :

WebDec 24, 2024 · Find the tangent line to the curve y = x2 at x = 1. Solution By formula ( [eqn:tangentline]), the equation of the tangent line is y − f(a) = f ′ (a) ⋅ (x − a) with a = 1 and f(x) = x2. So f(a) = f(1) = 12 = 1. Both the curve y = x2 and the tangent line pass through the point (1, f(1)) = (1, 1). WebThe slope is just the rate of change of a line. Or the rate of change of y, with respect to x, as we go along a line. And you could also view it as a measure of the inclination of a line. So the more incline the line is, the more positive of a slope it would have. So this right over here, this has a positive slope.
