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 )
Rearrange the given equation into this form
10x + 20y + 40 = 0 ( divide all terms by 10 to simplify )
x + 2y + 4 = 0 ( subtract x + 4 from both sides )
2y = - x - 4 ( divide all terms by 2 )
y = - [tex]\frac{1}{2}[/tex] x - 2 ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex] and y- intercept c = - 2
