is this right?

2x-y=3
-2x -2x
-y= -2x+3
-1(-y=-2y+3)
y= 2x - 3

the perpendicular line that would interesect that line at that point would be:
y = -1/2x +6

intersection (4.25, 5.5)
distance = √ 5.3125

is this right?

Does anyone know how to do this problem:

An offshore oil rig well is 4 kilometers off the coast. The refinery is 9 kilometers down the coast. Laying pipe in the ocean is twice as expensive as on land. What path should the pipe follow in order to minimize the cost? Complete the following statement.

The pipe should be laid in the ocean from the rig to a point on the coast_______km from the refinery, then on land the remainder of the distance to the refinery.

Thanks for any help!
