Question

determine a distancia entre os seguinte pares de pontos
a) A (0-2) e B (-6,-10)
1

b) A(-3,-1) e B (9,4)​

Answer 1

a) AB= √(Xb-Xa)²+(Yb-Ya)²

AB= √(-6-0)²+(-10-2)²

AB=√36+144

AB=√180

b) CD= √(9-(-3))² + (4-(-1))²

BC=√144+25

BC=√169

BC=13

EF= √(5-(-3))²+(1-7)²

EF= √64+36

EF= √100

EF= 10

GH= √(4-(-2))²+(-3-5)²

GH=√36+64

GH=√100

GH=10
