Answer:
unit rate is 36 tiles per square foot
Step-by-step explanation:
The unit rate can be found by calculating the slope of the linear graph.
calculate the slope m, using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
let (x₁, y₁ ) = (1, 36 ) and (x₂, y₂ ) = (6, 216) ← 2 points on the graph
substitute these values into the formula for m
m = [tex]\frac{216-36}{6-1}[/tex] = [tex]\frac{180}{5}[/tex] = 36
That is the unit rate is 36 tiles per square foot
