The straight line `x/a+y/b=1` cuts the coordinate axes at `A` and `B` . Find the equation of the circle passing through `O(0,0),Aa n dBdot`

Explanation

To find the equation of the circle passing through the points O(0,0), A(a,0), and B(0,b), we can follow these steps:

### Step 1: Identify the points A and B
The line given is \( \frac{x}{a} + \frac{y}{b} = 1 \).
- The point A is where the line intersects the x-axis. At this point, \( y = 0 \):
\[ \frac{x}{a} + \frac{0}{b} = 1 \implies x = a \implies A(a, 0) \]
