To find the equation of a line with a slope of -4 that passes through the point (-4, 14), we can use the point-slope form of a linear equation, which is given by:
\[ y - y_1 = m(x - x_1) \]
where \( m \) is the slope, and \( (x_1, y_1) \) is the point the line passes through.
Here, \( m = -4 \), \( x_1 = -4 \), and \( y_1 = 14 \). Substituting these values into the point-slope formula gives:
\[
y - 14 = -4(x + 4)
\]
Now, we can simplify this equation:
\[
y - 14 = -4x - 16
\]
Adding 14 to both sides:
\[
y = -4x - 16 + 14
\]
\[
y = -4x - 2
\]
Thus, the equation of the line is:
\[
y = -4x - 2
\]
\[ y - y_1 = m(x - x_1) \]
where \( m \) is the slope, and \( (x_1, y_1) \) is the point the line passes through.
Here, \( m = -4 \), \( x_1 = -4 \), and \( y_1 = 14 \). Substituting these values into the point-slope formula gives:
\[
y - 14 = -4(x + 4)
\]
Now, we can simplify this equation:
\[
y - 14 = -4x - 16
\]
Adding 14 to both sides:
\[
y = -4x - 16 + 14
\]
\[
y = -4x - 2
\]
Thus, the equation of the line is:
\[
y = -4x - 2
\]
