Finding the Coordinate of Point B

To find the coordinate of point B, given that point A is (3) and point C is (-7), we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint between two points (x1, y1) and (x2, y2) is given by:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

In this case, we have the coordinates of point A as (3) and point C as (-7). We can use these coordinates to find the coordinate of point B.

Calculation

Using the midpoint formula, we can calculate the coordinate of point B as follows:

Given: Point A = (3) Point C = (-7)

Using the midpoint formula: Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Substitute the given coordinates: Midpoint = ((3 + x2)/2, (-7 + y2)/2)

Now, we can solve for the unknown coordinate of point B.
