Answer:
5
Explanation:
The slopes of parallel lines are equal. The equation is already in slope-intercept form (y = mx + b) with m (the slope) being 5. Two lines are parallel if their slopes are equal and they have different y-intercepts (b). An example of a line that is parallel to (y = 5x + 3) could be (y = 5x + 1).
