Answer:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
A point in a coordinate plane is represented by using its x coordinate and y coordinate. If a point O has a x coordinate (a) and a y coordinate (b), it is represented as O(a, b)
The distance between two points with location at A([tex]x_1,y_1[/tex]) and point B([tex]x_2,y_2[/tex]) is the length of the line AB and is given by the formula:
[tex]D=|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
