Answer: 5
The Distance between the coordinates of two points is measured by distance formula.
Step-by-step explanation:
The Distance between the coordinates of two points P(x1,y1) and Q(x2,y2) is measured by 
Distance PQ=  (x2-x1)²+(y2-y1)²
(x2-x1)²+(y2-y1)²
So, the distance between (-1,4 ) and (2,0) can be calculated by
Distance=  (2-(-1))²+(0-4)²
(2-(-1))²+(0-4)²
               =  (3)²+(-4)²
(3)²+(-4)²
               = 9+16 =
9+16 =  25                                                  as
25                                                  as     25 = 5
25 = 5
Distance = 5
So the distance between the two coordinates is 5.
