Answer:
Explanation:
In 2D cartesian coordinates, distance between two points is given as:
⇒
d
=
√
(
x
2
−
x
1
)
2
+
(
y
2
−
y
1
)
2
So for our problem:
⇒
d
=
√
(
4
−
8
)
2
+
(
−
7
−
(
−
3
)
)
2
⇒
d
=
√
(
−
4
)
2
+
(
−
4
)
2
⇒
d
=
√
16
+
16
⇒
d
=
√
32
Now we can simplify by trying to find the largest square number we can pull out of the square root.
⇒
d
=
√
2
×
16
⇒
d
=
√
2
×
4
2
⇒
d
=
4

Answer:
32
Step-by-step explanation:
distance formula: (x2-x1)+(y2-y1)
(4-8)^2+(-7+3)^2
(-4)^2+(-4)^2
16+16
=32
