Answer:
The slope of the line is -1/2
Explanation:
The general equation of a line is

where
m is the slope of the line, which is the rate of change of the y-variable with respect to the x-variable
q is the y-intercept, which is the y-coordinate at which the line touches the y-axis
The equation of the line given in this problem is

Therefore, by comparing it with the general equation, we observe that:

Therefore, the slope of this line is -1/2.

The first character. geul, means orange, or tangerine.
The other two, euisang, mean clothes.
So put together, it basically means like 'tangerine clothes', or maybe 'orange costume'. With no other context I can't really tell what it exactly means.
I hope this helped anyway. ^^
