Find the distance of 35 to midpoint line between 30 and 05 T

Find the distance of (3,-5) to midpoint line between (3,0) and (0,5)! Thanks:)

Midpoint: (x1+x2/2, y1+y2/2)
Distance: (x^2 + y^2)

Solution

Answers to the question:

The midpoint is 3+0 /2 , 0+5/2 = 1.5,2.5

Distance = sqrt((3-1.5)^2 + (-5-2.5)^2) = 7.6485
