Step 1
Given points and , find a plane containing points and that is parallel to line .
Step 2
First, calculate the direction vector of the line through points and . This can be done by taking the coordinate values of point and subtracting them from point .
Step 3
Replace the , , and values and then simplify to get the direction vector for line .
Step 4
Calculate the direction vector of a line through points and using the same method.
Step 5
Replace the , , and values and then simplify to get the direction vector for line .
Step 6
The solution plane will contain a line that contains points and and with the direction vector . For this plane to be parallel to the line , find the normal vector of the plane which is also orthogonal to the direction vector of the line . Calculate the normal vector by finding the cross product x by finding the determinant of the matrix .
