# How do you write an equation for a circle with tangent to 3x - 4y + 3 = 0 at (-1,0) radius 7?

##### 1 Answer

#### Answer:

Thus, there are two circles satisfying the given cond.

#### Explanation:

Suppose that

Since, the pt. of contact

Also, line

As slope of tgt. is

But, slope of

Sub.ing in

So, the Centre is

the eqn. of the circle, is,

In this case, the Centre is

Thus, there are two circles satisfying the given cond.
