Answer:
1/3
Explanation:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Let's start at 0 with x = 0 and y = 0 or (0,0)
You see the graph crosses coordinate (3,1)
so y goes from 0 to 1 => rise = 1
x goes from 0 to 3 => run = 3
then rise/run = 1/3
