Best ResponseYou've already chosen the best response.1Each 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 \[(\frac{x_{point1} + x_{point2}}{2},\frac{y_{point1} + y_{point2}}{2})\]

Best ResponseYou've already chosen the best response.0So the two points given to me and put them into \[\frac{ x1+ x2 }{ 2 } + \frac{ y1 + y2 }{ 2 }\]

Best ResponseYou've already chosen the best response.1If 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

Best ResponseYou've already chosen the best response.1Not 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).
