Find the slope of the line that passes through (9, 6) and (4, 5).

boyakko [2]

Answer:

slope = $\frac{1}{5}$

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )

m = $\frac{5-6}{4-9}$ = $\frac{-1}{-5}$ = $\frac{1}{5}$
