Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The slope of [tex]\frac{y}{3}+\frac{2x}{5}[/tex] is -3. When a line is perpendicular to another, it's slope will be the negative reciprocal of the other line. -3 could also be written as [tex]-\frac{3}{1}[/tex] , and if you take the reciprocal, it would be [tex]-\frac{1}{3}[/tex] , and the negative form of this (since a negative plus a negative is a positive) would be [tex]\frac{1}{3}[/tex] .
