The required equation of the line is y=-4x

Step-by-step explanation:

Given : Points (0,0), (2,-8).

To find : What is the equation of the line ?

Solution :

Applying Two point slope form to find the equation,

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Where, (x_1,y_1)=(0,0) and (x_2,y_2)=(2,-8)

Substitute in the formula,

$(y-0)=\frac{-8-0}{2-0}(x-0)$

$y=\frac{-8}{2}x$

y=-4x

Therefore, The required equation of the line is y=-4x
