Answer:
slope = - 2, y- intercept = - 1
Explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 6x + 3y = - 3 into this form by subtracting 6x from both sides
3y = - 6x - 3 ( divide all terms by 3 )
y = - 2x - 1 ← in slope- intercept form
with slope m = - 2 and y- intercept c = - 1
