Determining a Cartesian equation given a point and a line

Click For Summary
SUMMARY

The discussion focuses on determining the Cartesian equation of a plane given a point P(-2,0,6) and a line represented by the equation "x-4/3= y+2/-5=z-1/2". The solution involves finding a directional vector from point P to the line's coordinates, resulting in a vector (6,-2,-5). The cross product of this directional vector and the line's directional vector (3,-5,2) yields (-29,-27,-24). Finally, the dot product of this cross product with the vector PA leads to the Cartesian equation of the plane.

Homework Statement



Given the point P(-2,0,6) and the line "x-4/3= y+2/-5=z-1/2" determine the cartesian equation of the plane.

Homework Equations


the lines vector equation is (4,-2,1)+T(3,-5,2)

The Attempt at a Solution


using A(x,y,z) i attempted to find a directional vector for P, PA=(x+2,y,z-6). I figured the dot product of PA nad the directional vector of the line would give me the cartesian equation but it doesn't satisfy the given answer.
help?

Nvm guys, i got it...you can find another directional vector using points P and the coordinate given in the lines equation. That will give you directional vector (6,-2,-5), with this you find the cross product of the two directional vectors giving you (-29,-27,-24).
Then take the original coordinate, and coordinate A(x,y,z), PA=x+2, y ,z-6). find the dot product of the cross product and PA, and itll give you the cartesian equation!
