Answer:
slope = - [tex]\frac{2}{9}[/tex]
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
2x + 9y = - 18 ( subtract 2x from both sides )
9y = - 2x - 18 ( divide all terms by 9 )
y = - [tex]\frac{2}{9}[/tex] x - 2 ← in slope- intercept form
with slope m = - [tex]\frac{2}{9}[/tex]
