The distance formula is given as:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates of the two points are:
Point 1: (-7, 7)
Point 2: (-7, 8)
Using the distance formula:
d = sqrt((-7 - (-7))^2 + (8 - 7)^2)
= sqrt((0)^2 + (1)^2)
= sqrt(0 + 1)
= sqrt(1)
= 1
Therefore, the distance between the points (-7, 7) and (-7, 8) is 1 unit.
