Explanation:
The formula to calculate the slope of a line is given by :-
![\text{Slope}=\frac{\text{Change in y coordinates}}{\text{Change in x coordinates}}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2lutw9y7csrbeg8s1xmi0c7ysvsg4w0yq9.png)
From the graph it can be seen that the line is passing from (0,-3) and (4,4), then the slope of the given line will be :-
![\text{Slope}=(4-(-3))/(4-0)\\\\\Rightarrow\text{Slope}=(7)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4cbhhhr2fii4ok9ehpp5z9ioluufy6pwpr.png)
Hence, the slope of the given line is graph =
