Explanation:
you marked the important pieces of information correctly.
a parallel line must have the same slope. otherwise it is tilted differently, and it is therefore not parallel.
the slope in a y = ... equation is always the factor of x.
in our case therefore 1/5.
so, the parallel line starts with
y = (1/5)x + b
and to get b we use the x and y coordinates of the given point :
3 = (1/5)×5 + b = 5/5 + b = 1 + b
b = 2
and our equation is
y = (1/5)x + 2
