well unless you meant to put a 5 in front of the x in the original problem none of those works

a 5

ok
so then the slope would flip over and become negative to become -1/5
then you would plug everything into point-slope form (y-y1)=m(x-x1)
y-3=-1/5(x-(-10))
distribute
y-3=-1/5x-2
add three
y=-1/5x+1
the answer is c
