Please consult the "Calculations" section of this ans .

The information we're given is below :
- slope : -1/3
- Point crossed by the line : (3, 6)
As per given information , we can do the following :
- Write the line's equation in point slope form
Point - slope form looks like so :
y-y₁=m(x-x₁)
y-6=-1/3(x-3)
y-6=-1/3x+1
y=-1/3x+1+7
y=-1/3x+6

Answer:
(x-8)/10
Step-by-step explanation:
-------
add up the X values and y values and divide by two
X=(-2+6)/2=2
Y=(-4=8)/2=2
