The equation of the line parallel to y = -1/2x+5 that passes through the point (2, -3) is y = -1/2x-2.

Explanation:

The slope of the line parallel to another line is the same as that of the other line. Therefore, the slope of the line parallel to y=-1/2x+5 is -1/2 because the slope of that line is -1/2.

Using point-slope form, y - y_1 = m(x-x_1) where y-1 and x_1 are points from a given coordinate pair (x,y) that lies on the line, and m is the slope.

Plugging in -1/2 for m, 2 for x_1, and -3 for y_1:
y-(-3) = -1/2(x-2)
y + 3 = -1/2x + 1
y = -1/2x -2
