One way to get shortest possible distance between a point and a line is to draw a line that passes through the given point (0,5) and is perpendicular to the give line (x+y=3), and then calculating the distance between the intersection point of these two line and the given point (0,5).
Given line here : x+y=3

Line perpendicular to given line: x-y = Constant (K). K can be calculated as this line passes through (0,5). K= -5.

Intersection point of these two lines will be (-1,4).

Distance between (0,5) and (-1,4) = √2

Quickest way is to remember the formula to find shortest distance between ax + by + c = 0 and (\(x_1\),\(y_1\)) = \(|ax_1+by_1+c|\) / \(\sqrt{a^2+b^2}\)
