Question

Coordinates of point P on a number line is -7. Find the coordinates of points on the number line which are at a distance of 8 units from point P.

Answer 1

$Given Coordinats\:of \: point \: P \:in \: number \: line \: is \: -7$

$i )The \:coordinates\: of \:points \:on \:the$

$number\: line\: which \:are \:at \:a \:distance$

$of \: 8 \: units\: from\: point \:P = P + 8$

$= - 7 + 8$

$\green {= 1}$

$ii )The \:coordinates\: of \:points \:on \:the$

$number\: line\: which \:are \:at \:a \:distance$

$of \: 8 \: units\: from\: point \:P = P - 8$

$= - 7 -8$

$\green {= -15}$

Therefore.,

$The \:coordinates\: of \:points \:on \:the$

$number\: line\: which \:are \:at \:a \:distance$

$of \: 8 \: units\: from\: point \:P \:are \: -15$

$and \: 1$
