Question

Imagine the scatter plot was created based on the data in the table. Which equation best represents the trend line for the data?

Answer 1

Using a graphing calculator, we will have the graph to look thus:

The equation that will fit the trend will be in the form:

`y=mx+c`

From the image above:

`\begin{gathered} m=0.60 \\ c=1.03 \end{gathered}`

So the equation will be:

`y=0.60x+1.03`

From the options given, the answer above can be rewritten as:

`\begin{gathered} y=(3)/(5)x+1 \\ \text{The correct answer is option C.} \end{gathered}`
