Use the slope to do
(-8-0)/(2-0)
-8/2 = -4
The slope is -4
y = -4x
Answer:
The required equation of the line is [tex]y=-4x[/tex]
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,
[tex](y-y_1)=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Where, [tex](x_1,y_1)=(0,0)[/tex] and [tex](x_2,y_2)=(2,-8)[/tex]
Substitute in the formula,
[tex](y-0)=\frac{-8-0}{2-0}(x-0)[/tex]
[tex]y=\frac{-8}{2}x[/tex]
[tex]y=-4x[/tex]
Therefore, The required equation of the line is [tex]y=-4x[/tex]
