Two lines are parallel if they have the same slope.
The slope of the line whose equation is: y= 1/5x - 15, is 1/5
The slope-intercept form of a line is:
y = mx + b
where m is the slope and y is the y-intercept
Replacing with the point (5, 6) and m = 1/5, we get:
6 = 1/5(5) + b
6 = 1 + b
6 - 1 = b
5 = b
Finally, the equation is:
y = 1/5x + 5
