Answer:
1. length of the segment = 5 units
2. length of the segment = 9.22 units
Explanation:
To find the length of a segment joining two points (x,y) and (x',y') we always use the formula
Distance between the points = √(x-x')²+(y-y')²
In our question the given points are (-1,6) and (-5,3) the distance between them will be = √(-1+5)²+(6-3)² = √4²+3² = √16+9 =√25 = 5 Units
2. Length between the points (-4,1) and (3,7) will be = √(-4-3)²+(1-7)²
= √(-7)²+(-6)² = √49+36 = √85 = 9.22 units
