# How do you find the missing coordinate if P=(4,-1) is the midpoint of the segment AB, where A=(2, 5)?

To find the missing coordinate of point B, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint (M) of a line segment with endpoints A(x₁, y₁) and B(x₂, y₂) can be found by taking the average of the x-coordinates and the average of the y-coordinates.

In this case, we are given that the midpoint (P) is (4, -1) and one endpoint (A) is (2, 5).

To find the missing coordinate of point B, we can use the midpoint formula:

x-coordinate of B = 2 * x-coordinate of P - x-coordinate of A y-coordinate of B = 2 * y-coordinate of P - y-coordinate of A

Plugging in the given values, we have:

x-coordinate of B = 2 * 4 - 2 = 6 y-coordinate of B = 2 * (-1) - 5 = -7

Therefore, the missing coordinate of point B is (6, -7).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
