19x+15y=-6 changed into slope intercept form.
attashe74 [19]

Answer:

y = - \frac{19}{15} x - \frac{2}{5}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

19x + 15y = - 6 ( subtract 19x from both sides )

15y = - 19x - 6 ( divide all terms by 15 )

y = - \frac{19}{15} x - \frac{6}{15}, that is

y = - \frac{19}{15} x - \frac{2}{5} ← in slope- intercept form
