Question

What is the equation of the following line? (0,0) (2,-8)

Answer 1

Use the slope to do

(-8-0)/(2-0)

-8/2 = -4

The slope is -4

y = -4x

Answer 2

Answer:

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 $y=-4x$
