Answer:
The slope of a line that is parallel to the line represented by the equation y = 5x + 3 is 5.
In general, when two lines are parallel, they have the same slope. So, if the equation of one line is in the form y = mx + b, where "m" is the slope, any line parallel to it will also have a slope of "m." In this case, the slope of the given line y = 5x + 3 is 5, so any line parallel to it will also have a slope of 5.
