Exercise 1
Determine the equations of the coordinate axes and the coordinate planes.
Exercise 2
Determine the equation of the plane that contains the lines:
Exercise 3
Determine the equation of the plane that contains the point A = (2, 5, 1) and the line:
Exercise 4
Find the intersecting point between the plane x + 2y − z − 2 = 0, the line determined by the point (1, −3, 2) and the vector 
.
Exercise 5
Determine, in intercept form, the equation of the plane that passes through the points A = (2, 0, 0), B = (0, 4, 0) and C = (0, 0, 7).
Exercise 6
π is a plane that passes through P = (1, 2, 1) and intersects the positive coordinate semi-axes at points A, B and C. If ABC is an equilateral triangle, determine the equations of π.
Exercise 7
Find the equation of the plane that passes through the point P = (1, 1, 1) and is parallel to:
Exercise 8
Determine the equation of the plane that contains the line 
and is parallel to the line 
.
Exercise 9
Calculate the equation of the plane that passes through the point (1, 1, 2) and is parallel to the following lines:
Solution of exercise 1
Determine the equations of the coordinate axes and the coordinate planes.
x - axis O = (0, 0, 0) 
= (1, 0, 0)
y - axis O = (0, 0, 0) 
(0, 1, 0)
z - axis O (0, 0, 0) 
= (0, 0, 1)
XOY O = (0, 0, 0) = (1, 0, 0) = (0, 1, 0)
z = 0
XOZ 0 = (0, 0, 0) = (1, 0, 0) 
= (0, 0, 1)
y = 0
YOZ O = (0, 0, 0) = (0, 1, 0) = (0, 0, 1)
x = 0

Solution of exercise 6
π is a plane that passes through P = (1, 2, 1) and intersects the positive coordinate semi-axes at points A, B and C. If ABC is an equilateral triangle, determine the equations of π.
A = (a, 0, 0) B = (0, b, 0) C = (0, 0, c)
As the triangle is equilateral, the three line segments are equal.
Solution of exercise 7

Solution of exercise 8
Determine the equation of the plane that contains the line and is parallel to the line .
The point A = (2, 2, 4) and the vector 
belong to the plane because the line is in the plane.
The vector 
is a vector in the plane because it is parallel to the line.
Solution of exercise 9
Calculate the equation of the plane that passes through the point (1, 1, 2) and is parallel to the following lines:
