Question
Find the point on the line-5x + 4y-1 0 which is closest to the
point (-3, 4).
Hint:
- Part 1: Write y as a linear function of the variable x.
y = (5x+1)/4
%3D
Part 2: Find the function f(x) that can be used to minimize this distance using
the hint, if necessary. Remember, root is not needed.
f(x) =
Part 3: Find the first derivative of f(x) with respect to x.
Part 4: Find the coordinates of the point on the line -5x +4y +-1 = 0
that is closest to the point (-3,4).
