In order to determine what is the slope of the given line, use the following formula for m:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]where (x1,y1) and (x2,y2) are two points of the line.
From the graph you can notice that two points can be:
(x1,y1) = (-2,0)
(x2,y2) = (0,4)
replace the values of all coordinates into the formula for m:
[tex]m=\frac{4-0}{0-(-2)}=\frac{4}{2}=2[/tex]Hence, the slope of the given line is m = 2
