To write the linear equation in point-slope form, we can use the point-slope formula:
\[
y - y_1 = m(x - x_1)
\]
where \( (x_1, y_1) \) is a point on the line and \( m \) is the slope.
In this case, the point is \( (−14, 8) \) and the slope \( m = -3 \).
Substituting these values into the formula gives:
\[
y - 8 = -3(x - (-14))
\]
Simplifying, this becomes:
\[
y - 8 = -3(x + 14)
\]
Thus, the correct response is:
**y + 8 = -3(x + 14)**
\[
y - y_1 = m(x - x_1)
\]
where \( (x_1, y_1) \) is a point on the line and \( m \) is the slope.
In this case, the point is \( (−14, 8) \) and the slope \( m = -3 \).
Substituting these values into the formula gives:
\[
y - 8 = -3(x - (-14))
\]
Simplifying, this becomes:
\[
y - 8 = -3(x + 14)
\]
Thus, the correct response is:
**y + 8 = -3(x + 14)**
