Question

1. Draw a quadrilateral in the Cartesian plane, whose vertices are (–4, 5), (0, 7), (5, –5)
and (–4, –2). Also, find its area.
2. find the equation of the line which passes through (2,2 square root 3) and is
enclined with the x axis at an angle of 75degrees.
3. find the distance of the point (-1,1) from the line 12 (x+6) = 5(y-2).
4. show that the points (-2,3,5), (1,2,3) and (7,0, -1) are collinear.
5. find the equation of the set of points P, the sum of whose distances from A(4,0,0)
and B (-4,0,0) is equal to 10.
