Communicate how can you find what each mark represents on a number line
To find the coordinate of the midpoint of a line segment, you can use the midpoint formula.
Midpoint = (Endpoint1 + Endpoint2) / 2
In this case, the endpoints are -9 and 6.
Midpoint = (-9 + 6) / 2
Midpoint = -3 / 2
Midpoint = -1.5
Therefore, the coordinate of the midpoint of the segment is -1.5.
To find the coordinate of the midpoint of a line segment on a number line, you need to find the average of the two endpoint coordinates. In this case, the endpoints are -9 and 6.
To find the average, add the two endpoints and divide by 2:
(-9 + 6) / 2 = -3 / 2 = -1.5
Therefore, the coordinate of the midpoint of the segment is -1.5.
