Tangents And Normals

​

Intro 

​Tangent :

M_T = -5, Point (-2,5)

y = mx + c

5 = -5(-2) + c

c = -5

Equation :

y_T = -5x - 5

​Normal :

M_N = 1/5, Point (-2,5)

y = mx + c

5 = 1/5 (-2) + c

c = 27/5

Equation :

y_N = 1/5 x + 27/5

(x5)

5y = x + 27

​Tangent :

M_T = 3, point (3,-7)

y = mx + c

-7 = 3(3) + c

c = -16

Equation :

y_T = 3x - 16

​Normal :

M_T = -1/3 , Point(3,-7)

y = mx + c

-7 = -1/3(3) + c

c = -6

Equation :

y_N = -1/3 x - 6

(x3)

3y = -x - 18
