y=−x−5

Answer 1

To find the equation of the line in slope-intercept form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept, we can use the point-slope form of the line equation, which is given by:

\[
y - y_1 = m(x - x_1)
\]

where \( (x_1, y_1) \) is a point on the line, and \( m \) is the slope.

Given that the point is \( (-5, 3) \) and the slope \( m \) is \( -1 \), we can substitute these values into the point-slope form:

\[
y - 3 = -1(x + 5)
\]

Now, we can simplify this equation step-by-step:

1. Distribute the slope on the right side:

\[
y - 3 = -x - 5
\]

2. Add 3 to both sides to isolate \( y \):

\[
y = -x - 2
\]

Now we have the equation of the line in slope-intercept form. Therefore, the correct response is:

\[
y = -x - 2
\]

So, the answer is: **y = −x − 2**.
