1.	Distance of (4,a) from its X-axis is half the distance from Y-axis ,find the value of a
Answer» Distance of point from x-axis\xa0{tex}= \| a \|{/tex}Distance of point from y-axis\xa0= 4A.T.Q.{tex}\| a \| = \\frac { 1 } { 2 } \\times 4{/tex}{tex}\\Rightarrow \| a \|{/tex}\xa0= 2{tex}\\Rightarrow{/tex}\xa0{tex}a = \\pm 2{/tex}
