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:

yy1=m(xx1)

where (x_1, y_1) is the point on the line. Plugging in our values:

y3=1(x(5)) y3=1(x+5) y3=x5

Next, we simplify it:

y=x5+3 y=x2

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").
