Step-by-step Solution
The given linear function in point-slope form is
\[
y + 7 = -\frac{1}{2}(x - 14).
\]
In point-slope form, the equation is expressed as
\[
y - y_1 = m(x - x_1),
\]
where \( m \) is the slope and \( (x_1, y_1) \) is a point on the line.
From the given equation, we can identify the slope \( m \) as
\[
-\frac{1}{2}.
\]
To find the point \( (x_1, y_1) \), we can rewrite the equation in the standard point-slope form:
\[
y - (-7) = -\frac{1}{2}(x - 14).
\]
This shows that \( y_1 = -7 \) and \( x_1 = 14 \). Therefore, the point on the line that the equation is based on is
\[
(14, -7).
\]
In summary:
- The slope of the line is \( -\frac{1}{2} \).
- The point on the line is \( (14, -7) \).
Quick Answer
The slope is \( -\frac{1}{2} \) and the point is \( (14, -7) \).
