Question

Find the distance between the following pair of points.
(-a,-b) & (a,b)
with using this formula:
$ab = \sqrt(x2 - x1 {)}^{2} + (y2 - y1 {)}^{2}$


​

Answer 1

Answer:

(-a,-b)&(a,b)

Step-by-step explanation:

P(-a,-b) Q(a,b)

PQ=√(x2-x1)^2+(x2-x1)^2

PQ=√(a-(-a))^2+(b-(-b))^2

PQ=√(a+a)^2+(b+b)^2

PQ=(a+a)+(b+b)

PQ=2a+2b,,
