Answer: 7 is the distance in between the points
Step-by-step explanation: How you find the distance between points is pretty simple once you know how to do it!
So first take your X coordinate take the first one (8) and subtract it from the second one (4) 8-4=4 so now we have 4 put that aside for a moment,
Now take your Y coordinate subtract the first one (10) from the second one (7), 10-7=3
Finally add the 3 and 4 together you get 7 that is why 7 is the distance in between the points
