Find the distance on the coordinate system from the point (-3, 4) to the point (8, -7).

Answer 1

remember the pythagorean theorem?
this is like that
the distance is the hypotnuse

D=
`\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}`

D=
`\sqrt{(8-(-3))^(2)+(-7-4)^(2)}`
D=
`\sqrt{(11)^(2)+(-11)^(2)}`
D=
`√(169+169)`
D=
`√(338)`
D=
`11√(2)`
