Find the distance between the points (3,9) and (


7,

7).

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

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

In this case, the points are (3, 9) and (-7, -7). Plugging these values into the distance formula:

d = sqrt((-7 - 3)^2 + (-7 - 9)^2)

Simplifying:

d = sqrt((-10)^2 + (-16)^2)

d = sqrt(100 + 256)

d = sqrt(356)

Therefore, the distance between the points (3, 9) and (-7, -7) is sqrt(356).
