Find the point B if M is the midpoint of the line segment joining points A and B.

A(−1, −8), M(6, −1) Using these two points I have to figure out what B is. I'm not terribly good at math and I would love to know how to do this.

Instead of memorizing the formula, just think of a midpoint as the average of the x values and the average of the y values.
You find the average of two numbers by adding them and dividing by 2.
