Solution:
(1) Midpoint:
A point in the middle of the line segment that divides it into two equal parts.
Mid point formula:
![$\left((x_(1)+x_(2))/(2), (y_(1)+y_(2))/(2)\right)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ezukd0c6qf9rdzjvvcwpk3n4lzfq4ib3za.png)
Middle of a segment; in the form of a coordinate plane.
(2) Slope:
To find the slope of the line when passing through two points.
Slope formula:
![$(y_1-y_2)/(x_1-x_2)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/dvouzedvc617awqr2sxekc99voiaxc9xrn.png)
(3) Distance:
To find the distance of two points.
Distance formula:
![√((x_1-x_2)^2+(y_1-y_2)^2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/ov9v2zuctbn89auyhhh0zgghbc5eddjnoq.png)
