Analytic geometry in the plane

Problem 1. Coordinates of points М₁, М₂ and the equation of straight line d are given. It is required:

1. Construct a straight line d and points М₁ and М₂;

2. Calculate the distance from the point М₁ to the straight line d;

3. Write the equation of the straight line passing through the point М₁, parallel to the straight line d;

4. Write the equation of the straight line passing through the point М₂ is perpendicular to straight line d;

5. Write the equation of the straight line passing through the points М₁ and М₂;

6. Determine a relative position of straight lines М₁М₂ 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.
