Question

1. Use the distance formula (FOR COORDINATES) to find the distance between A(-6, 4) and B(5,-3).

Answer 1

Answer:
`√(170)`

Explanation:

Distance formula: a^2+b^2=c^2 where c is the distance between two points

(-6-5)^2 + (4-(-3))^2=c^2

(-(6+5))^2 + (4+3)^2=c^2

(-11)^2 + 7^2=c^2

121 + 49=c^2

c^2=170

c=
`√(170)` ==> distance between A and B
