Question

. Find the distance between the following pairs of points:
i. (a,b), (-a, -b )​

Answer 1

Answer:

2 * (sqrt(a^2+b^2))

Step-by-step explanation:

By distance formula

Distance between points (a,b) & (-a,-b) is

sqrt{((a-(-a))^2+ ((b-(-b))^2}

= sqrt{(2a)^2+ (2b)^2} = 2 * (sqrt(a^2+b^2))
