Given:
A line passes through the point,

The slope of the line is m = -1.
The objective is to find the equation of the line in point-slope and slope-intercept form.
Step-by-step explanation:
To find equation in point-slope form:
The general formula of point-slope form is,

On plugging the given values in equation (1),

To find the equation in slope-intercept form,
The general formula of slope-intercept form is,

On further solving the equation (2),

Hence,
The equation of the line in point-slope form is y+6 = -x+5.
The equation of the line in slope-intercept form is y = -x-1.
