Question 580
Parallel lines have the same slope. Using the formula y = mx + b where m is the slope and b is the y-intercept, we know that the slope of both lines is 5.
 
Since the coordinates of the origin are (0, 0), we know that the y-intercept of the new line is 0.
 
So, the equation of the new line can be written as y = 5x + 0 or y = 5x
