Assignment 7
The line goes through the points
and
and intersects the line:
in point .
Calculate the coordinates of .
Solution
The equation of the line is not yet known and has to be determined. We can calculate the slope
of
with:
Now we have the slope of we can calculate the equation and therefore we have to choose one of the points
and
. We choose the point
, so:
We find the -coordinate of the intersection point
by solving:
and thus we have:
The intersection point has the coordinates
.
Check this in the figure.
