Answer: The slope of the green line is 3
Explanation:
Given: Two lines graphed are parallel.
One of them is red and another is red with slope 3.
We know that the slopes of parallel lines are equal.
Therefore if the slope of the red line is 3 and red line and green lines rae parallel lines, then both the slopes of both the lines area equal i.e. 3.
Hence, the slope of the green line is 3.
