Distance is calculated by the square root of (x2-x1)^2 + (y2-y1)^2
We simply substitute the values into this formula 
Square root of (3--5)^2 + (0-1)^2
Which is 8
        
             
        
        
        
The shaded region is above the line so it would be y> so then the equation is y=4x+2 since the graph has a y intercept of 2 and a slope of four
tl;dr the answer is B
