The point slope form of the equation for line passes through (0, -5) with slope 2 is (y+5) = 2 (x-0)
<u>Solution:
</u>
In the question it is given that the line passes through the point (0,-5) with slope (m) = 2. We have to find out the point slope form of the equation.
We know the point - slope form of an equation is given by
![\left(y-y_{1}\right)=m\left(x-x_{1}\right)](https://tex.z-dn.net/?f=%5Cleft%28y-y_%7B1%7D%5Cright%29%3Dm%5Cleft%28x-x_%7B1%7D%5Cright%29)
where
are the x and y co-ordinates
![\text { Here } y_{1}=-5 \text { and } x_{1}=0 \text { and the slope } m=2](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Here%20%7D%20y_%7B1%7D%3D-5%20%5Ctext%20%7B%20and%20%7D%20x_%7B1%7D%3D0%20%5Ctext%20%7B%20and%20the%20slope%20%7D%20m%3D2)
Substituting the values in the point slope form of the equation we get
(y-(-5)) = 2 (x-0)
⇒ (y+5) = 2 (x-0)
Hence the point slope form of the equation for line passes through (0, -5) with slope 2 is (y+5) = 2 (x-0)
