Hi Lia W
We need to know what kind and version of graphing calculator you need instructions on
The Graphing Calculator at Desmos.com has a set of short videos that can show you how to plot your points
Since your question says which system of equations is represented by the lines q and v, are there choices of systems for you to select from? Such as
y - 3x = 27
6y + 3x = 48
or
y - 3x = 27
y + x/2 = 8
y = 3x + 27
y = -x/2 + 8
To use the graphing calculator you can establish a relationship based on the information in the tables
Since you are given a table for each line you can put your lines Slope Intercept Form
y = mx + b
First use two points to calculate the slope m
Second use the third point to calculate b
You can use the established Slope Intercept Lines at Desmos.com
You can also check the very short videos at Desmos.com that will show you how to plot the points in your tables and connect them with lines
I hope this helps you
