Answer:
X= 1/2 y= -2/5. X+2y= -1/5.
The equation of the line passing through the point with coordinates (1/2, -2/5) and having slope -1/2 is:
y = -1/2x + b.
Substituting coordinates of the point in the equation, we get:
-2/5 = -1/2(1/2) + b => b = 1/5.
Therefore, the equation of the line is:
y = -1/2x + 1/5.
