Answer:

- 0.4

Step-by-step explanation:

The radius of a circle and a tangent to the circle are perpendicular to each other at the point of contact.

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2.5}[/tex] = - 0.4

Answer:

-0.4

Step-by-step explanation:

Given

Let r = radius

r = -2.5

The relationship between the slope of the tangent of the line and the radius is as follows;

Let ∆s represent slope

Mathematically, ∆s = -1/r

Substitute 2.5 for r

∆s = -1/2.5

∆s = -0.4

Hence, given that the radius of circle is 2.5, the slope of the line tangent to is -0.4
