PB is a line segment on a number line, it has endpoints at -2 and 12. What are the coordinates of its midpoint?
To find the coordinate of the midpoint, we can use the midpoint formula, which states that the coordinate of the midpoint of a line segment is the average of the coordinates of its endpoints.
In this case, the coordinates of the endpoints are -2 and 12. To find the average, we sum up the coordinates and divide by the number of endpoints:
(-2 + 12) / 2 = 10 / 2 = 5
Therefore, the coordinate of the midpoint of PB is 5.
To find the coordinates of the midpoint, we can use the midpoint formula, which states that the midpoint of a line segment is the average of the coordinates of its endpoints.
Let's label the coordinates of the endpoints as A and B, with A at -2 and B at 12.
The x-coordinate of the midpoint is given by the formula:
midpoint_x = (x1 + x2) / 2
Substituting the values, we get:
midpoint_x = (-2 + 12) / 2
midpoint_x = 10 / 2
midpoint_x = 5
Therefore, the x-coordinate of the midpoint is 5.
Since the line segment is on a number line, there is no y-coordinate.
Hence, the coordinates of the midpoint are (5, 0).
