Answer:
slope = -

Explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 18x + 4y = 122 into this form
Subtract 18x from both sides
4y = - 18x + 122 ( divide all terms by 4 )
y = -
x +
← in slope- intercept form
with slope m = -
= -
