Analytic geometry in the plane.

Problem 1. Coordinates of points Ì1, Ì2 and the equation of straight line d are given. It is required:

1. construct a straight line d and points Ì1 and Ì2;

2. Calculate the distance from the point Ì1 to the straight line d;

3. Write the equation of the straight line passing through the point Ì1, parallel to the straight line d;

4. write the equation of the straight line passing through the point Ì2 is perpendicular to straight line d;

5. write the equation of the straight line Ì1 Ì2;

6. determine a relative position of straight lines Ì1 Ì2 and d; if they are not parallel, to determine the tangent of the angle between them and find the coordinates of the point of their intersection.
