Answer:

Circle equation : x^2+y^2=25

To find :

The equations of the tangents with the slope 2

Step-by-step explanation:

let the general equation of a tangent : y = mx + c

where 'm' is the slope and 'c' is y intercept ;

general condition :

=> c^2 = a^2 (1+m^2)

for the given circle :

=>  a^2 = 25 ;

=> a = 5 ;

given m = 2 ;

=> c^2 = 25(1 + 2^2)  = 25*5 = 125

=> c = ± 5\sqrt[]{5} ;

Hence, equation of tangents :

y = 2x ± 5√5
