Midpoint Formula: X1+X2/2 , Y1+Y2/2
=> 2+(-8)/2 , -6+5/2
=> -6/2 , -1/2
=> -3 , -1/2
Hence coordinates are ( -3,-1/2)
In science, a formula, such as a mathematical formula or a chemical formula, is a brief way to convey information symbolically. The basic concept of a relationship between specified quantities is referred to as a formula in informal science usage.
A truth or a rule expressed using mathematical symbols is the formula. An equal sign is typically used to connect two or more values. When you are aware of the value of one quantity, you can use the formula to determine the value of the other.
