Step-by-step explanation:
in moving from the point let say A(7,0) to the point B(-1,3), the x-coordinate increases by (7-(-1)= 8 while the y-coordinate decreses by (0-3)=-3. The same of this is given by finding the square of 8=64 and (-3)=9. by summing the two we have 64+9=73. so we find the square root of 73 which which is 8.55. so therefore the answer is 8.55 which is approximately 9
