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]
