Find the value of n.
Given that a line passes through the points (9, 3), (12, 4), and (n, -5).
First we find the equation of the line that. passes through the points (9,3), and (12,4).
The equation of a line passing through the points
In this problem
This implies that
. Plugging these values
Therefore, the equation of the line is
Also given that the line passing through the point
Thus, the value of n is -15,
