Question

find the distance between the point (a,b) and (-a, -b ).​

Answer 1

Step-by-step explanation:

fotmula

(m1.x2+m3.x1)/m1.m2

this is for (x)

(m1.y2+m2.y1)/m1.m2

this is for (y=)

Answer 2

$\huge\boxed{\fcolorbox{cyan}{pink}{Solution:--}}$

Distance formula:-

${ \pink{ \boxed{ \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} } }}}$

Now putting the values:-

$\implies\sqrt{( - a - a) {}^{2} + ( - y - y) {}^{2} } \\ \\ \implies \: \sqrt{ (- 2a) {}^{2} + ( - 2y) {}^{2} } \\ \\ \: \implies \sqrt{4a {}^{2} + 4y {}^{2} } \\ \\ \implies \sqrt{4(a {}^{2} + y {}^{2} } \\ \\ \implies</strong><strong>{ \pink{ \boxed {2 \sqrt{a {}^{2} + y {}^{2} } }}}$
