To find the equation of the line in slope-intercept form (y = mx + b), we start with the slope and the point given.
1. The slope (m) is -1.
2. The line passes through the point (-5, 3). This means that when x = -5, y = 3.
We can use the point-slope form of the equation of a line first:
\[ y - y_1 = m(x - x_1) \]
where (x_1, y_1) is the point on the line. Plugging in our values:
\[ y - 3 = -1(x - (-5)) \]
\[ y - 3 = -1(x + 5) \]
\[ y - 3 = -x - 5 \]
Next, we simplify it:
\[ y = -x - 5 + 3 \]
\[ y = -x - 2 \]
So, the equation in slope-intercept form is:
**y = -x - 2**
The correct response from the options provided is:
**y = -x - 2** (or "y equals negative x minus 2").
