First, locate two points and locate the coordinates of the two points
Let choose (0, 9)
and (6,7)
Using the slope formula:
[tex]\text{slope}=\frac{y_{2\text{ - }}y_1}{x_2-x_1}[/tex]
x₁= 0 y₁ = 9
x₂= 6 y₂=7
Substitute the values into tha formula;
[tex]\text{slope =}\frac{7-9}{6-0}[/tex]
[tex]=\frac{-2}{6}[/tex][tex]=-\frac{1}{3}[/tex]
[tex]\text{slope}=-\frac{1}{3}[/tex]
