We can use the distance formula to find the distance between two points:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
Using the coordinates (-8, 5) and (4, 0), we get:
distance = sqrt((4 - (-8))^2 + (0 - 5)^2)
distance = sqrt((12)^2 + (-5)^2)
distance = sqrt(144 + 25)
distance = sqrt(169)
distance = 13
Therefore, the distance between the points (-8, 5) and (4, 0) is 13 units.
