Answer:
= sqrt(221)≈ 14.86606875
Explanation:
To find the distance between two points (x1,y1,) and (x2,y2) we use the formula
d= sqrt((x2-x1)^2 + (y2-y1)^2)
Since the points are (-5,-2) and (9,-7) we can substitute them into the formula
d= sqrt(( -7--2)^2 + (9--5)^2)
= sqrt((-7+2)^2 + (9+5)^2)
= sqrt((-5)^2 + (14)^2)
= sqrt(25+ 196)
= sqrt(221)
≈ 14.86606875
