Answer: -2/5
Step-by-step explanation: the slope of a line is the one that describes the direction and inclination of that line. When two lines are parallel, it means that they have the same slope. To determine the slope of a line, we need to isolate "y" and the slope will be the number that is with the "x," the procedure is shown as follow:
5y+2x=12
isolating y:
5y=12-2x
y=(12-2x)/5
the number that is with the "x" is -2/5 so that is the slope.
