Question

Find the difference between AB A(5,8) and b(1,2)

Answer 1

Step-by-step explanation:

i guess it's Distance

Distance Formula = √(x2 - x1 )² + (y2 -y1)²

√(1-5)² + (2-8)²

√(-4)² + (-6)²

√(16) + (36)

√4(4+ 9)

2√13 units

ANSWER

M is a point which divides the line segment AB internally in the ratio 1:2 because it is on AB and not on the extended portion of AB.

To find the coodrinates of a point (X,Y) which divides a line segment joining (xA,yA) and (xB,yB) internally in the ratio m:n, we use the formula:

X=m+nmxB+nxA and 

Y=m+nmyB+nyA

So the point M can be found with the formula:

xM=32xA+xB=32×2−1=1 and 

yM=
