La ecuación de la recta que pasa por los puntos (2,-1) y (1,-5) es: y= 4x+9

y= 4x-9

y= x-9

ninguna de las anteriores

Given:

A line passes through the points (2,-1) and (1,-5).

To find:

The equation of the line.

Solution:

If a line passes through the two points, then the equation of the line is

The line passes through the points (2,-1) and (1,-5). So, the equation of the line is

Using distributive property, we get

Subtract 1 from both sides.

Therefore, the correct option is B.
