Steps for graphing this in Excel. I DO NOT need anything eith Q or the equation or any math at all whatsoever, simply the steps on how to graph all three groups of watershed data $($a$,$ b$,$ and c$)$ on the same scatter plot graph. That is all.

$3.$ When rain falls over an area for a sufficiently long time, it will run off and collect at the bottom of hills and eventually find its way into creeks and rivers. A simple way to estimate the maximum discharge flowrate $Q($in units of cubic feet per second $[[$:$f\frac{t^3}{s}\})$ from a watershed of area $A($in units of acres$)$ with a rainfall intensity $i($in units of inches per hour $[$in$/$h$])$ is given by an expression commonly called the Rational Method, as

$Q=$CiA

Values of $C$ vary between about $0($for flat rural areas$)$ and almost $1($in urban areas with a large amount of paved area$).$

A survey of a number of rainfall events was made over a $10-$year period for three different watersheds. The data that resulted is given in the following table. Watershed A is $120$ acres, $B$ is $316$ acres, and $C$ is $574$ acres.

Create a graph containing all three watersheds, with flowrate on the ordinate, and fit linear trendlines to obtain a simple model for each watershed.
