whats the distance between (1,1) and (-2,1)
The distance between two points can be calculated using the distance formula:
Distance = √[(x2-x1)^2 + (y2-y1)^2]
In this case, point A is (1,1) and point B is (-2,1).
Plugging in the values:
Distance = √[(-2-1)^2 + (1-1)^2]
Distance = √[(-3)^2 + 0^2]
Distance = √[9]
Distance = 3
Therefore, the distance between point A (1,1) and point B (-2,1) is 3 units.
