The slope of a line passing through two points is given by the formula:
m = (y2 - y1) / (x2 - x1)
For the line labeled lowercase r passing through points F(-5, 3) and G(3, 3):
m = (3 - 3) / (3 - (-5))
m = 0 / 8
m = 0
Therefore, the slope of line r is 0.
A line parallel to line r will also have a slope of 0, so the answer is B.
A graph plots a point labeled uppercase F at (negative 5, 3) and a point labeled uppercase G at (3, 3). A bidirectional arrow labeled lowercase r passes through the points F and G.
