the equation in slope-intercept form:
y=mx%2Bb

given:
(5, 2) and (6,+1)
use given points to find slope m
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m=%281-2%29%2F%286-5%29
m=-1%2F1
m=-1
so far equation is
y=-x%2Bb.........plug in coordinates of one point to find b
2=-5%2Bb
b=2%2B5
b=7

equation is
y=-x%2B7
