Given data:
The given equation of the line is y=7/4x+4/7.
The standard expression for the equation of the line is,
y=mx+c
Compare the given equation with the above expression.
m=7/4
Two parallel lines have equal slope, the slope of the line n whhich is parallel to the first line is,
m'=m
m'=7/4
Thus, the slope of the lline which is parallel to the given line is m'=7/4.
