Answer:
slope = 40
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 80) and (x₂, y₂ ) = (4, 160) ← 2 points on the line
m = [tex]\frac{160-80}{4-2}[/tex] = [tex]\frac{80}{2}[/tex] = [tex]\frac{40}{1}[/tex] = 40
