Final answer:
The slope of a line parallel to 10m + 12y = -120 is -10/12.
Step-by-step explanation:
The equation of the line is 10m + 12y = -120.
To find the slope of the line, we need to rewrite the equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Dividing both sides of the equation by 12, we get: m = (-10/12).
The slope of any line parallel to this line will also be (-10/12).
