Find the slope of the given line on the graph. REMEMBER: Rise over run! <br> Pls show work!

Leviafan [203]

Answer:

the slope is $-\frac{1}{3}$

Step-by-step explanation:

Notice that you are given two points to use for the slope calculation:

$(x_1,y_1)=(-4,4) \,\,and\,\, (x_2,y_2)=(5,1)$

So we use the formula for the slope of a line given two points:

$slope\,=\,\frac{y_2-y_1}{x_2-x_1} \\slope\,=\,\frac{1-4}{5-(-4)} \\slope\,=\,\frac{-3}{9} \\slope\,=\,-\frac{1}{3} \\$
