Final answer:
The distance between the points (7, 8) and (-8, 0) on a coordinate grid is 17 units.
Step-by-step explanation:
The distance between two points in a coordinate grid can be found using the distance formula:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates of the first point are (7, 8) and the coordinates of the second point are (-8, 0).
Substituting these values into the formula:
distance = sqrt((-8 - 7)^2 + (0 - 8)^2)
distance = sqrt((-15)^2 + (-8)^2)
distance = sqrt(225 + 64)
distance = sqrt(289)
distance = 17
Therefore, the distance between the two points is 17 units. The correct answer is D) 16 units.
