Answer:
The equation of the line k is

Step-by-step explanation:
Given that k is perpendicular to line m, defined as:
y = 3x - 1
the slope of k is the negative reciprocal of the slope of line m.
The slope of m is 3
The negative reciprocal of m is -1/3 (this is the slope of k)
Therefore, k is in the form

Since this line passes through the point (x, y) = (-4, 3), we can use this to obtain the value for the y-intercept, b

Solving for b by subtracting 4/3 from both sides

The equation is therefore,
