In order to graph this equation, you have to isolate y.

3x + 5y = -2

3x + 5y + 2 = 0

3x + 2 = -5y

(3x+2)/-5 = y

Now you can plug it into a graphing calculator.

If you're graphing by hand, the equation you'll want to use is:

(-3/5)x - (2/5) = y

So the slope will be negative 3/5 and the y-intercept is -2/5.
