Is there a mistake in the problem statement? In question 4.1, B is (-8; 1), but to show that M is (-4; 3), B must be (-8; -2). Also, DA is a tangent to the circle at A, and D(3; -1), but if M(-4; 3) a

Here's a step-by-step solution to the problem.

Important Note on Discrepancies:
There are inconsistencies in the problem statement:

1. The text states B(-8; 1), but to "show that" M is (-4; 3) in question 4.1, B must be (-8; -2). We will proceed with B(-8; -2) to satisfy 4.1.
2. The text states "DA is a tangent to the circle at A" and gives D(3; -1). However, if M(-4; 3) and A(0; 8), the line through A and D is not perpendicular to the radius MA. We will assume the primary definition: the tangent at
