Answer:
Slope = -1/3
Explanation:
The below formula can be used to find the slope of a line;
[tex]\text{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the given graph in the question, we can read off the coordinates of x and y at the two dotted points on the straight line as follows;
[tex]\begin{gathered} y_1=-1,x_1=3 \\ y_2=1,x_2=-3 \end{gathered}[/tex]
We can go ahead and substitute the above values into our equation and find the slope of the line;
[tex]\begin{gathered} \text{Slope}=\frac{1-(-1)}{-3-3} \\ =\frac{1+1}{-6} \\ =\frac{2}{-6} \\ \therefore Slope=-\frac{1}{3} \end{gathered}[/tex]
So the slope of the line is -1/3
