Answer:
yards =
feet
Step-by-step explanation:
The graph is a straight line passing through the origin with equation
y = mx ( m is the slope )
Calculate slope using gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 2) ← 2 points on the line
m =
=
= 
the x- axis is feet and the y-axis is yards, hence
yards =
feet
