S(-3,0) & y(1,-3)
you can multiply y by 5 then calculate or you multiply by 5 in the equation
so you take (x) of s and subtract it from 5(x) of y and add it to (y) of s subtarcted from 5(y) of y then make radical for the formula
s - 5y =  \sqrt{( - 3 - 5(1)) {}^{2}  + (0 - 5( - 3)) {}^{2} }  =  \sqrt{64 + 255}  =  \sqrt{289}  = 17
