Let us mark the points as A(-3,-4),B(5,-7).
Then distance between the points is
AB={5-(-3)}+{-7-(-4)}
    =8+(-3)
    =5 units.
 The distance between the points is 5 units.

Given points are (-3,-4) & (5,-7)
distance between two points (x1,y1) & (x2,y2) = {(x2-x1)² + (y2-y1)²}^1/2
so distance = {(5+3)² + (-7+4)²}^1/2
                  = (64+9)^1/2
                  = √71
