In order to convert an equation in slope-intercept form ($$y=mx+b$$) into standard form, you must understand a few rules. I will list them for you:

1. $$Ax+Bx=C$$ is the form of the linear function

2. $$A,B,C\in\mathbb{Z}$$ (A, B, and C must be integers)

3. $$A\geq0$$

4. A,B, and C must be co-prime

Knowing these rules, let's now convert $$y=-\frac{2}{5}x-5$$ into standard form:

 $$y=-\frac{2}{5}x-5$$ Because standard form does not allow there to be fractions, let's eliminate the current fraction by multiplying all sides by 5. $$5y=-2x-25$$ Add 2x to both sides. $$2x+5y=-25$$ We have converted the equation from slope-intercept form while meeting all the conditions.
