what is the slope of the line on this graph?

Answer: 3
Step-by-step explanation:
The slope of a line passing through two points (a,b) and (c,d) is given by :-
[tex]\text{Slope}=\dfrac{d-b}{c-a}[/tex]
In the given graph , the line is passing through (0,0) and (1,3) .\
Then the slope of line passing through (0,0) and (1,3) will be :-
[tex]\text{Slope}=\dfrac{3-0}{1-0}\\\\\Rightarrow\ \text{Slope}=3[/tex]
Hence, the slope of the given line= 3
