Answer:

The distance from a point to the line

d = (9)/(√(10) )

Explanation:

Explanation:-

Given straight line y = 3x-9 and point ( 0, 3)

Given straight line 3 x - y -9 =0

The distance from a point to the line

$d = \frac{ax_(1) +by_(1) +c_(1) }{\sqrt{a^(2) +b^(2) } }$

$d = |\frac{3(0) -3 -9 }{\sqrt{3^(2) +1^(2) } }|$

d = (9)/(√(10) )
