Answer:

(1;-4)

Explanation:

The point of intersection is a point where the two graphs are equal, therefore it is a point where:

2x - 6 = -2x - 2

Now solve for x:

4x = 4
x = 1

Now that we have our x value, we can substitute it back into either equation to get our y value:

y = 2x - 6
y = 2(1) - 6
y = -4

Therefore your coordinates are (1;-4)
