Answer:
slope = [tex]\frac{6}{5}[/tex] , price of 1 bottle = $1.20
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 ) = (0, 0) and (x₂, y₂ ) = (5, 6) ← 2 points on the line
substitute these values into the formula for m
m = [tex]\frac{6-0}{5-0}[/tex] = [tex]\frac{6}{5}[/tex]
The price of 1 bottle is then 6 ÷ 5, that is
price of 1 bottle = 6 ÷ 5 =$1.20
