Question 624307
Note: the length of the segment is the same as the distance between the two points.


d = sqrt((x2-x1)^2+(y2-y1)^2)



d = sqrt((-3-1)^2+( 6- 1)^2)



d = sqrt((-4)^2+(5)^2)



d = sqrt(16+25)



d = sqrt(41)



So exact distance between the two points is  sqrt(41)  units.


Therefore, the approximate length of the segment is about 6.403 units (use a calculator to evaluate the square root of 41)
