False

3)

Sonja's house is 4 blocks west and 1 block south of the center of town. Her school is 3 blocks east and 2 blocks north of the center of town.

What is the direct distance from Sonja's house to her school?

(Hint: The center of town should be the origin, and north is up.)

10 blocks
4.5 blocks
7.1 blocks
7.6 blocks

Answer 1

1) false we have to use distance formula
2) true
3) \[\sqrt{(x1-x1)^{2}+(y1-y2)^{2}}\]
= rt ov (3+4)^2 + (2+1)^2
=rt ov 49+9
=rt ov 58 = 7.6
