Final answer:
The exact vertical shift when translating from point P to point P' is calculated by subtracting the y-coordinate of P from the y-coordinate of P', which is answer choice C.
Step-by-step explanation:
The calculation that gives the exact vertical shift of a translation from point P to point P' is the y-coordinate of P' minus the y-coordinate of P. When translating a point in the coordinate system, the vertical shift is determined by the change in the y-coordinates. Therefore, the correct answer is C. The y-coordinate of P' minus the y-coordinate of P.
To determine the displacement vector, for a point that starts at b(6.0, 1.6) and ends at e(2.0, 4.5), we would use the provided coordinates to find the scalar components Dx and Dy. The displacement in the y-direction would be calculated as Dy = ye - yb. Similarly, in the x-direction, it would be Dx = xe - xb. By applying this understanding, we confirm that vertical displacement directly relates to the y-coordinates of the initial and final positions.
