Work Step by Step
Slope of a line is the ratio that compares the change in y (the rise) to the change in x (the run)
$m=\displaystyle \frac{\text{change in y}}{\text{change in x}}$
For each line we take (0,0) as an initial point, and then interpret the slope to find another point on the line.
$ m=-1=\displaystyle \frac{-1}{1} \quad$ change x by 1, y by -1
$(0,0) \quad \rightarrow\quad(1,-1)$
$ m=\displaystyle \frac{-1}{2} \quad$ change x by $2$, y by $-1$
$(0,0) \quad \rightarrow\quad(2,-1)$
$ m=0=\displaystyle \frac{0}{1} \quad$ change x by 1, y by 0
$(0,0) \quad \rightarrow\quad(1,0)$
$ m=\displaystyle \frac{1}{3} \quad$ change x by $3$, y by $1$
$(0,0) \quad \rightarrow\quad(3,1)$
$ m=2=\displaystyle \frac{2}{1} \quad$ change x by $1$, y by $2$
$(0,0) \quad \rightarrow\quad(1,2)$
