Answer 1

c

Answer 2

we can see if it is directly above,below,right,or to the left
assume n is positive
if you have (a,b) and you want the point n units directly above then the point is (a,b+n).
if you have (a,b) and you want the point n units directly below then the point is (a,b-n).
if you have (a,b) and you want the point n units directly to the right then the point is (a+n,b).
if you have (a,b) and you want the point n units directly to the left then the point is (a-n,b)

no sometimes it isn't directly to the right,to the left, or up or down
sometimes you have to use
\[d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\]
and check that d is actually 10 in your case where (x1,y1)=(-3,-5)
