Answer:

y = -x + 3

Explanation:

First find the slope (rise over run):


((5-1)/(-2-2)) = (4)/(-4) = -1

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:

y = -x + 3

Answer:

equation : y = -x + 3

Step-by-step explanation:

  • coordinates given: (-2,5) and (2, 1)

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
