Find the distance bw (h,k) where for x axis

1.	Find the distance bw (h,k) where for x axis
Answer» The distance of the point (h, k) from x-axis i.e. distance between (h,k) and (x,0) is{tex}Distance=\\sqrt{(x-h)^2 +(0-k)^2}{/tex}\xa0[By using distance formula]{tex}\\Rightarrow Distance=\\sqrt{x^2+h^2-2xh+k^2}{/tex}{tex}\\Rightarrow Distance=\\sqrt{x^2+h^2+k^2-2xh}{/tex}
