Answer:

[tex]\huge\boxed{y-27=8(x-3)}[/tex]

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

where

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (3, 27) and (-8, -61).

Calculate the slope m:

[tex]m=\dfrac{-61-27}{-8-3}=\dfrac{-88}{-11}=8[/tex]

Susbtitute to the equation of a line:

[tex]y-27=8(x-3)[/tex]
