A circle has centre (C(2,-1)) and radius (5). An external point (P(10,3)) is given. Find the equations of the lines through (P) that are tangent to the circle. Give your answers in the form (y = mx + c).

Answer Options

A. y = (96+30√15)\/238 x + (3-10(96-30√15)\/238) and y = (96-30√15)\/238 x + (3-10(96+30√15)\/238)
Correct Answer B. y = (96+30√15)/238 x + (3-10(96+30√15)/238) and y = (96-30√15)/238 x + (3-10(96-30√15)/238)
C. y = (96+30√15)\/240 x + (3-10(96+30√15)\/240) and y = (96-30√15)\/240 x + (3-10(96-30√15)\/240)
D. y = (96+30√15)\/238 x + (3+10(96+30√15)\/238) and y = (96-30√15)\/238 x + (3+10(96-30√15)\/238)
Correct Answer
B
Correct Option:
y = (96+30√15)/238 x + (3-10(96+30√15)/238) and y = (96-30√15)/238 x + (3-10(96-30√15)/238)
