In order to find the distance between the given points, use the following formula:
where (x1,y1) and (x2,y2) are the given points,
In this case, you have:
(x1,y1) = (1 , 4)
(x2,y2) = (7 , 12)
By replacing the previous values into the formula for d, you obtain:
Hence, the distance between the given points is 10
