Answer:

$\frac{5}{2}$

Step-by-step explanation:

recall for a line whose equation is

y = mx + b,

the slope of this line is m

the slope of a line that is perpendicular to this line is - $\frac{1}{m}$

in this case,

m = - $\frac{2}{5}$

hence - $\frac{1}{m}$ = $\frac{5}{2}$

1 / 10 is the easiest answer. Remember ratios are just percentages. It could also be 2/20, 3/30, as long as it is 10%.
