Answer:
y = -3x + 20.
Explanation:
The correct point-slope equation of a line with slope -3 that contains the point (8,-4) is:
y - (-4) = -3(x - 8)
Expanding the right-hand side:
y + 4 = -3x + 24
Subtracting 4 from both sides:
y = -3x + 20
Therefore, the answer is not given in any of the options provided. The correct equation is y = -3x + 20.
