Basically, a well is a hole drilled into the ground to access water contained in an aquifer. A pipe and a pump are used to pull water out of the ground, and a screen filters out unwanted particles that could clog the pipe. Wells come in different shapes and sizes, depending on the type of material the well is drilled into and how much water is being pumped out.

Answer:
-1/2
Explanation:
Solving the equation for y, we can find the slope of the given line. It is the coefficient of x.
y = 2x -5 . . . . . slope = 2
The slope of the perpendicular line will be the opposite reciprocal:
m = -1/2 . . . . . slope of perpendicular line
