Question

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

Answer 1

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).
