Here are some videos to watch to introduce midpoint and distance formulas. Both formulas are on the formula chart.
The midpoint formula is used to find the COORDINATES of the middle point that lies between two points on a coordinate plane. For example, what is the coordinates of the midpoint between (2,5) and (6, 8). Well the midpoint formula would use these two points and find the coordinates of the midpoint between the two given points.
The distance formula finds the distance between two given points. You could use the same (2,5) and (6,8) and plug them into the distance formula to find the length of the segment that connects the two points together.
Watch the videos and take notes and write down the examples. Take notes over the videos and put them in the "notes, handouts" sections of your binder."
