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 slope and the given point.

Given:
- Slope (m) = -1
- Point (x, y) = (−5, 3)

Using the point-slope form of the equation of a line, which is given by:

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

Substituting in the values:

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

This simplifies to:

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

Distributing the -1:

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

Adding 3 to both sides:

\[ y = -x - 2 \]

So, the equation of the line in slope-intercept form is:

**y = -x - 2**

The correct response is:

**y = −x − 2**.
