If a line passing through the origin touches the circle `(x-4)^2+(y+5)^2=25` , then find its slope.

`pm3//4`

`pm3`

`pm1`

Text Solution

Verified by Experts

The correct Answer is:

Radius of the circle = 5 and y- coordinate of its centre = - 5
`rArr` The circle touches x-axis.
Therefore slope=0
