Write an equation of each line in standard form with integer coefficients. Y=-3/5*+3

What we are going to do is to reverse the process of putting an equation in slope intercept form ...

y = - 3/5x + 3 (the 3 needs to be a fraction with denominator of 5)

y = - 3/5x + 15/5 (now, let's multiply each side by 5 to remove fractions)

5y = - 3x + 15 (add 3x to each side of the equation)

3x + 5y = 15 (this is now in standard form)
