Answer:
The slope of the line is 3
Step-by-step explanation:
we know that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
[tex]rise=y2-y1[/tex]
[tex]run=x2-x1[/tex]
therefore
The formula to calculate the slope between two points is equal to
[tex]m=\frac{rise}{run}=\frac{y2-y1}{x2-x1}[/tex]
take two points from the graph
(0,-1) and (1,2)
[tex]rise=2+1=3[/tex]
[tex]run=1-0=1[/tex]
[tex]m=\frac{3}{1}=3[/tex]
