Question

find the equation of the line AB
find the equation of the tangent line T​

Answer 1

Step-by-step explanation:

a) Slope of line AB= (5-3)/(4-2)

= 1

Equation of line AB : (y-3) = 1(x-2)

: x-y+1=0

b) Slope of tangent will be = -1

Equation of tangent : (y-5) = -1(x-4)

: y-5 = -x+4

: x+y-9=0
