Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
A circle has an infinite number of lines of symmetry.
The answer would be $18,540 because you multiply 530 by 18 which gives you 9540 then you add 9000 to 9540 which adds up to $18,540
