Answer:
y=-x+4
Step-by-step explanation:
Since the lines are parallel, the slopes are going to be the exact same. In this case, the slope is -1.
Since we've been given a point and a slope, we can put this information into point-slope form.
y-y1 = m(x-x1), where x1 and y1 are any given points and m is the slope.
So,
y-0=-(x-4)
y=-x+4
