Answer:
To find the distance between point A and point B on a coordinate plane, we can use the distance formula. The distance formula is derived from the Pythagorean theorem and allows us to calculate the straight-line distance between two points. The distance formula is: d = √((x2 - x1)^2 + (y2 - y1)^2) where (x1, y1) are the coordinates of point A, and (x2, y2) are the coordinates of point B. Using the given coordinates for point A (-1, -4) and point B (-2, -3), we can substitute the values into the distance formula: d = √((-2 - (-1))^2 + (-3 - (-4))^2) = √((-2 + 1)^2 + (-3 + 4)^2) = √((-1)^2 + (1)^2) = √(1 + 1) = √2 Therefore, the distance between point A and point B is √2 units.
