Answer:

[see below]

Explanation:

Finding Slope:

m =
(rise)/(run)=(0-2)/(3-1)=(-2)/(2)=-1

Using the slope and a point to make a point slope equation:


y-y_1=m(x-x_1)

m = -1 (x,y) = (1,2)

Plug values:


y-2=-1(x-1)

Convert the equation into slope-intercept:


y-2=-1(x-1)\\\\y-2=-1x+1\\\\y-2+2=-1x+1+2\\\\y=-1x+3\\\\\boxed{y=-x+3}

Hope this helps.

y=-1x+3

I honestly have no idea how I would explain this. Apologies.
