A line passing through
graph{1/4x-1 [-7.82, 12.18, -4.6, 5.4]}
Explanation:
We need to find two points, then join up the line. The natural points to go for are those on the x-axis and the y-axis.
To find the point where it crosse the y-axis:
Let
You can also tell this from the value of
Now to find where it crosses the x-axis:
Let
We can now join up these two points like so:
graph{1/4x-1 [-7.82, 12.18, -4.6, 5.4]}
