Step-by-step explanation:
Answer:
The correct option is A.
Step-by-step explanation:
The first line passing through the points (-6,2) and (-6,0).
The slope of a line is

The slope of first line is

The second line passing through the points (0,-4) and (-1,1). The slope of second line is

The third line passing through the points (0,-6) and (2,-6). The slope of third line is

The fourth line passing through the points (0,6) and (-3,-7). The slope of fourth line is

Since the slope of a vertical line is infinity, Therefore option A is correct.
-3/5 = -6/10
9/10 - 6/10 = 3/10
