Final answer:
The value of a is 1 and the value of b is 0.0211.
Step-by-step explanation:
To find the value of a and b, we need to find the coordinates of points C and D. Since the line segment is trisected, we can use the section formula. The x-coordinate of C is the average of the x-coordinates of A and B, which is 3. The y-coordinate of C can be found using the section formula: a = -4 + (2/3)(2 - (-4)). Solving for a, we get a = 1. The x-coordinate of D can also be found using the section formula: b = 2 + (2/3)(5 - 2). Solving for b, we get b = 0.0211.
