Answer:

To find the distance between two points (x1, y1) and (x2, y2), we can use the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using the points (5, -7) and (9, 12), we get:

distance = sqrt((9 - 5)^2 + (12 - (-7))^2)

distance = sqrt(4^2 + 19^2)

distance = sqrt(16 + 361)

distance = sqrt(377)

Therefore, the distance between (5, -7) and (9, 12) is sqrt(377) units.
