To find the length of the red line segment in the coordinate plane, we can use the distance formula:
√( (x2 - x1)^2 + (y2 - y1)^2 )
Using the coordinates provided:
x1 = 4, y1 = 3
x2 = -2, y2 = -1
Plugging the values into the formula:
√( (-2 - 4)^2 + (-1 - 3)^2 )
= √((-6)^2 + (-4)^2)
= √(36 + 16)
= √52
≈ 7.21 units
Therefore, the length of the red line segment is approximately 7.21 units.
From the given statements, the statement "The length is √40 units; find the sum of the vertical and horizontal distances squared and then take the square root" is true.
