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.
Answer:
- y = -5
- x = - 2
=============================
The horizontal line has same y- coordinate for each x- coordinate, and is parallel to the x-axis so it is:
- y = - 5
The vertical line has same x- coordinate for each y- coordinate, and is parallel to the y-axis so it is:
- x = - 2
