First, find the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1)
m = (-3 - 1) / (4 - (-6))
m = -4 / 10
m = -2/5
Now that we have the slope, we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
Using the point (-6, 1):
y - 1 = (-2/5)(x - (-6))
y - 1 = (-2/5)(x + 6)
y - 1 = (-2/5)x - 12/5
y = (-2/5)x - 12/5 + 1
y = (-2/5)x - 12/5 + 5/5
y = (-2/5)x - 7/5
Therefore, the equation of the line passing through the points (-6, 1) and (4, -3) is y = (-2/5)x - 7/5.

I apologize for my mistake. Let's redo the calculation to avoid errors.
Using the formula for the slope:
m = (y2 - y1) / (x2 - x1)
m = (-3 - 1) / (4 - (-6))
m = -4 / 10
m = -2/5
Now, let's use the point-slope form of the equation of a line using the point (-6, 1):
y - y1 = m(x - x1)
y - 1 = (-2/5)(x - (-6))
y - 1 = (-2/5)(x + 6)
y - 1 = (-2/5)x - 12/5
y = (-2/5)x - 12/5 + 1
y = (-2/5)x - 12/5 + 5/5
y = (-2/5)x - 7/5
The equation of the line passing through the points (-6, 1) and (4, -3) is y = (-2/5)x - 7/5. This time, the calculation was correct.
