Answer:
y = - [tex]\frac{1}{5}[/tex] x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 20y = - 180 ( subtract 4x from both sides )
20y = - 4x - 180 ( divide all terms by 20 )
y = [tex]\frac{-4}{20}[/tex] - [tex]\frac{180}{20}[/tex] , that is
y = - [tex]\frac{1}{5}[/tex] x - 9 ← in slope- intercept form
