Answer:
15
Explanation:
Step one
Given data
The point coordinate is E(5,-1), F(-4,11)
Hence
x1=5
y1=-1
x2=-4
y2= 11
Step two
Required
Distance between the two coordinate point
Applying the Pythagoras theorem for the distance between two points
d=√((x2-x1)²+(y2-y1)²)
d=√((-4-5)²+(11-(-1))²)
d=√-9²+12²
d=√81+144
d=√225
d=15
Hence the Distance the points is 15
