Answer:

5.5

Step-by-step explanation:

The <em>rate of change</em> of a relationship is the <em>ratio of corresponding changes in value</em>. Symbolically, we indicate a change with the greek letter Δ (pronounced "delta"). A <em>change in x</em> is written Δx ("delta eks") and a <em>change in y</em> is written Δy ("delta why"). We're looking for the ratio Δy/Δx ("delta y over delta eks").

Mathematically, Δx and Δy are the <em>differences</em> between two corresponding x an y values. To pick these, we can take any two rows in our table. Let's pick rows 4 and 2, nice whole numbers:

\Delta{x}=20-10=10\\\Delta{y}=112-57=55\\\Delta{y}/\Delta{x}=55/10=11/2=5.5

We can confirm that this holds for every other pair, too - picking rows 2 and 1 as an example:

\Delta{x}=10-5=5\\\Delta{y}=57-29.5=27.5\\\Delta{y}/\Delta{x}=27.5/5=275/50=11/2=5.5

Reduce 720/1080 little cunfused
Veronika [31]
To reduce a fraction, divide the numerator and the denominator equally until they reach the simplest whole number possible. 

In this case, the numerator (720) and the denominator (1080) can both be divided by 360 to get 2/3, our reduced fraction.
