Answer: B) y = 1/2x

Step-by-step explanation:

In a perpendicular line, the slope is the opposite reciprocal. Thus, the equation can be simplified into y = 1/2x+b. Then, to get b, simply plug in 4 for x and 2 for y

2=1/2(4)+b

2=2+b

0=b

Thus, the equation of the line is y = 1/2x + 0, or y = 1/2x
