steposvetlana [31]

Answer:

The coordinates of his position is (-6,-8).

Step-by-step explanation:

Consider the provided information.

Let's assume for a moment that we are standing at the origin and the positive y-axis points due North while the positive x-axis points due East.

North represents the positive y axis, then south will represents the negative y axis.

It is given that the east represents the positive x axis then west represents the negative x axis.

Sasquatch-o-meter tells us that Sasquatch is 6 miles West and 8 miles South of our current position.

6 miles west represents a x=-6 and also 8 miles south represents y=-8

Thus, the coordinates of his position is (-6,-8).
