The slope-intercept equation of the parallel line is: C. y = 1/2x - 2.
The lines that are parallel to each other have the same slope value.
Given, y = 1/2x + 6, the slope is 1/2. This means that the line that is parallel to it will also have a slope, m = 1/2.
Substitute m = 1/2, and (x, y) = (0, -2) into y = mx + b to find b:
-2 = 1/2(0) + b
-2 = 0 + b
b = -2
Substitute b = -2 and m = 1/2 into y = mx + b
y = 1/2x - 2
