Question

the equation of tangent at point (x1,y1) having slope m1 is obtained by​

Answer 1

Given : a tangent at point  ( x₁ , y₁) with slope m₁

Step-by-step explanation:

Point ( x₁ , y₁)

Slope = m₁

Equation of a line at any point ( h , k) with slope m  is given by

y - k = m(x - h)

Hence Equation of tangent  at point ( x₁ , y₁) having Slope = m₁

would be

y  -  y₁ = m₁ (x - x₁)

y  -  y₁ = m₁ (x - x₁)  is the equation of tangent at point ( x₁ , y₁) having slope m₁
