Answer:
y = -1/6x -8
Explanation:
The slope-intercept form of the equation for a line can be found by solving for y. The slope-intercept form is ...
y = mx + b . . . . . . line with slope m and y-intercept b
__
3x +18y = -144
18y = -3x -144 . . . . . subtract 3x
y = -3/18x -144/18 . . . . divide by 18
y = -1/6x -8 . . . . . . . simplify
