How to find the shortest distance between 2 points

20.       Find the shortest distance from the given point to the given line.  Round to the nearest tenth, if
necessary.

Y =-2/3x+5

            a)         ( 0 , 0 ) and                     b)         ( 6 , 5 ) and 7x + y + 23 = 0

distance formula: d = sqrt [ (x2 - x1 )^2 + ( y2 - y1 )^2 ]
