Circle A is centered about the origin and has a radius of 5. What is the equation of the line that is tangent to Circle A at the point (–3,4)?

3x – 4y = –25

3x – 4y = 25

3x + 4y = –25

-3x + 4y = –29

Give the equation, in slope-intercept form, of the line tangent to the circle of the equation

x^2+y^2=225

at the point (12,−9).

y = (4/3)x−25

y = -(4/3)x−25

y = (4/6)x−25

y = (4/3)x−20

Give the equation, in slope-intercept form, of the line tangent to the circle of the equation

x^2−6x+y^2−91=0

at the point (−3,8).

y = 3/4x + 41/4

y = 3/4x + 41/6

y = -3/4x + 41/4

y = 3/4x - 41/4
