Step-by-step explanation:
[tex]\bold{METHOD\ 1:}\\\\\text{look at the picture}\ \#1\\\\\text{The fomula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{Form the graph wi hate points:}\\\\(-1, 3)\ \text{and}\ (0, -1).\\\\\text{Substitute:}\\\\m=\dfrac{-1-3}{0-(-1)}=\dfrac{-4}{1}=-4[/tex]
[tex]\bold{METHOD\ 2:}\\\\\text{look at the picture}\ \#2\\\\slope=\dfrac{rise}{run}\\\\rise=-4\\run=1\\\\slope=\dfrac{-4}{1}=-4[/tex]
