Answer:
Slope=1/3
Explanation:
we kown,
m=y2-y1/x2-x1
then you should take two point where line should be passing through these two pionts.
In graph you can see that (0,2) and(-3,1) are passing points of the line.
Here, x1=0
x2= -3
y1=2
y2=1
Now,
m= 1-2/ -3-0
= -1/ -3
=1/3
So, The slope of the line is 1/3.
I hope this will be helpful for you.
