### 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.
