Use the distance formula: (d=sqrt{(x_2-x_1)^2+(y_2-y_1)^2})
Identify the coordinates of the two points: ((x_1,y_1)) and ((x_2,y_2))
Subtract the x-coordinates: (x_2-x_1)
Subtract the y-coordinates: (y_2-y_1)
Square both differences
Add the squared values
Take the square root of the sum
The result is the distance between the two points
