Question

what is the distance between the y axis and line × = -3​

Answer 1

Answer:

$point \: on \: x = - 3 \: is \: \: ( - 3 \: \: \: \: \: \: \: 0) \\ \\ \\ point \: on \: y \: axis \: \: \: (0 \: \: \: \: \: \: \: 0) \\ \\ \\ \\ \\ \\ therefore \: \: required \: distance \: = \: \sqrt{ {(0 + 3)}^{2} + {(0 - 0)}^{2} } = 3 \: units$
