Answer:
slope = - [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
calculate the slope m, using the slope formula
• m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
let (x₁, y₁ ) = (10, 7 ) and (x₂, y₂ ) = (1, 8 )
substitute these values into the formula for m
m = [tex]\frac{8-7}{1-10}[/tex] = [tex]\frac{1}{-9}[/tex] = - [tex]\frac{1}{9}[/tex]
