Step-by-step explanation:
Gradient is just another similar term for slope l,
, and it can be calculated by
where
and 1
is the
-coordinates of point 
We let
be point
and
be point
, we can then write the equation:
.
It also says that the points are with a gradient of
so
. We can then write the equation:
