Answer:
(2.2, 0.5, 1.1)
Step-by-step explanation:
The parametric equation of the line normal to the plane and through point (2, 0, 1) can be written ...
... L = (2, 0, 1) + t(2, 5, 1)
We want to find the value of t (and the corresponding point) that makes L satisfy the equation of the plane.
... 2(2+2t) +5(0 +5t) +1(1+t) = 8 . . . . . put values from L in for x, y, z in plane
... 5 + 30t = 8 . . . . . simplify
... t = (8 -5)/30 = 0.1 . . . . solve for t (subtract 5, divide by 30)
For this value of t, L is ...
... (2, 0, 1) + 0.1(2, 5, 1) = (2.2, 0.5, 1.1)
