A line passes through #(9 ,2 )# and #( 4, 5 )#. A second line passes through #( 4, 1 )#. What is one other point that the second line may pass through if it is parallel to the first line?

Explanation:
Two parallel lines have the same gradient.
When we calculate the gradient of the first line,
gradient =
The gradient of the second line will also be
We already have the coordinates
Now let's say that it passes through the point
We can take
This is to simplify later, we can take any number for
So
gradient =
So the coordinates of a second point are
