Answer:
Six units of y per unit of x
Step-by-step explanation:
The unit rate is how much of something per unit of something else. In math, it corresponds to the slope of a line.
Your table probably looks something like this:
[tex]\begin{array}{cc}\mathbf{x} &\mathbf{y} \\3 & 16 \\5 &28 \\7 & 40 \\9 & 52 \\11 & 64 \\\end{array}[/tex]
Your bar (column) graph probably resembles the one below.
The unit rate is the slope of a line through the tops of the bars.
Draw points at the midpoints of the bars, then draw the best line that passes as close as possible to all the points.
It looks like the line passes through all the points.
To determine the slope, I chose (3, 16) and (11, 64).
Slope =(change in y)/(change in x)= Δy/Δx
Δy = y₂ - y₁ = 64 -1 6 = 48
Δx = x₂ - x₁ = 11 - 3 = 8
Slope = Δy/Δx = 48/8 = 6
The unit rate is six units of y per unit of x.
