Answer:
15 units
Explanation:
The distance between two points in a two-dimensional coordinate system can be calculated using the distance formula, which is derived from the Pythagorean theorem. The distance formula is:
d = √((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them.
In this case, the coordinates of the two points are:
Point 1: (12, -7)
Point 2: (-3, -7)
Plugging these values into the distance formula, we get:
d = √((-3 - 12)^2 + (-7 - (-7))^2)
Simplifying further:
d = √((-15)^2 + (0)^2)
d = √(225 + 0)
d = √225
d = 15
So, the correct answer is 15 units.
