B. y= -4x + 28
Step-by-step explanation:
To find the equation of this line first put it into slope-point form, 
where 
and 
are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,
First, distribute the -4
y-8=-4x+20
Next, add 8 to both sides
y=-4x+28
