The slope of a line that is parallel to the given line with a slope of 3 is also 3, as parallel lines have identical slopes.
The question is asking for the slope of a line parallel to a given line on a graph. To determine the slope of a parallel line, we can use the fact that parallel lines have identical slopes.
According to the information provided, the line in question has a slope of 3, which means for every increase of 1 on the horizontal axis (x), there is a rise of 3 on the vertical axis (y). Therefore, the slope of a line that is parallel to the given line would also be 3.
