The distance between the two points is 5 units
The formula for calculating the distance between two points is expressed as:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate points 1,2) and (5,5). Substitute the given coordinates into the formula as shown:
[tex]D=\sqrt{(5-1)^2+(5-2)^2}\\D=\sqrt{4^2+3^2}\\D=\sqrt{16+9}\\D=\sqrt{25}\\D=5units[/tex]
Hence the distance between the two points is 5 units
