How do you write the point slope form of the equation given (0,9) and (-2,11)?
First, we need to find the gradient of the line.
Then I will male the second set of coordinates (-2, 11) where
The gradient can also be written like this:
Now, we have value which we can put in:
The equation of a line can be found using either of our set of coordinates, where either:
I will be putting (0,9) in so:
The equation of the line is
