Answer:
y = -x + 3
Explanation:
First find the slope (rise over run):
Since the slope is -1, use one of the given coordinates to write an equation in point-slope form:
y - 5 = -1(x + 2)
or optionally in slope-intercept form:
equation : y = -x + 3
Step-by-step explanation:
slope = ( y2-y1 ) / ( x2-x1 )
= ( 1 - 5 ) / ( 2 --2)
= -4 / 4
= -1
Now find equation using: y - y1 = m ( x - x1 )
: y - 1 = -1 ( x - 2 )
: y = -x +2 +1
: y = -x + 3
