    Each variable (like x, y) is the average of whatever two points you want the midpoint of. So \[x_{midpoint} = \frac{x_{point1} + x_{point2}}{2}\] And \[y_{midpoint} = \frac{y_{point1} + y_{point2}}{2}\] So, you're coordinate - whatever it is - will be \[(\frac{x_{point1} + x_{point2}}{2},\frac{y_{point1} + y_{point2}}{2})\]

    So the two points given to me and put them into \[\frac{ x1+ x2 }{ 2 } + \frac{ y1 + y2 }{ 2 }\]

    If you check it out, you'll see that the average of two numbers is the number precisely between them. Conceptually, you are looking at the point that is halfway between the x's and halfway between the y's. That point is the "midpoint". |dw:1347917647774:dw|

    Not quite, actually, but very close! You don't add them, you separate them with a comma! The role of the formula, by it's nature really, just gives you a point. So you'll need it to look like one: (x, y).
