2. What is the slope of this line?

Answer:
m=3
Step-by-step explanation:
[tex]From\ the\ graph\ we\ observe\ that,\ \\Co-ordinate pair of Point 1 = (x_1,y_1) = (2,1)\\Hence,\\x_1=2, y_1=1\\Co-ordinate pair of Point 2 = (x_2,y_2) = (3,4)\\Hence,\\x_2=3, y_2=4\\Hence,\\We\ know\ that,\\\frac{Rise(y)}{Run(x)} =m\\m=\frac{y_2-y_1}{x_2-x_1 } \\m=\frac{4-1}{3-2}\\m=3[/tex]
