from 4 to 7 is 3 steps left
from -5 to -9 is 4 steps down

Answer 6

you got the mother of all right triangles there a 3 - 4 - 5 right triangle, making your distance 5

Answer 7

Answer is 5 then?

Answer 8

if you are a slave to formulas you can compute
\[\sqrt{(7-4)^2+(-5+9)^2}=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5\] but that is way too much work

Answer 9
