Write the equation in standard form using integers: y = - 2/5x - 3

Let's assume you meant y = (-2/5) x - 3.

-2/5x could be misinterpreted.

First, clear out the fraction (s). To do this, mult. both sides of the above eq'n by 5.

Result: 5y = - 2x - 15. Add 2x to both sides. The resulting equation is what you wanted: an equation in the form Ax + By = C (standard form).
