Find the Distance between the points A (2,3) and B (-1,-1)
just use the distance formula:
d = √((-1-2)^2 + (-1-3)^2) = √(9+16) = 5
To find the distance between two points in a coordinate plane, you can use the distance formula. The formula is:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Now, let's apply this formula to find the distance between points A (2, 3) and B (-1, -1).
x1 = 2, y1 = 3 (coordinates of A)
x2 = -1, y2 = -1 (coordinates of B)
Distance = sqrt((-1 - 2)^2 + (-1 - 3)^2)
= sqrt((-3)^2 + (-4)^2)
= sqrt(9 + 16)
= sqrt(25)
= 5
So, the distance between points A (2, 3) and B (-1, -1) is 5 units.
