If the slope of the given line is $m$ then the slope of the perpendicular would be the negative reciprocal. That is $-1/m$ .

Our line is $y=4/7x + 4$
This is in $y=mx+b$ form where $m$ is slope and $b$ is the y-interecept.

We can see the slope of the given line $m=4/7$

Therefore the slope of the perpendicular is given by $-1/(4/7)$

Which is $-7/4$

Answer
The slope of perpendicular to $y=4/7x +4$ is $-7/4$
