What is the graph of the linear equation x - 2y = 6?

First, solve for two points which solve the equation and plot these points:
First Point: For
x
=
0
0
−
2
y
=
6
−
2
y
=
6
−
2
y
−
2
=
6
−
2
y
=
−
3
or
(
0
,
−
3
)
Second Point: For
y
=
0
x
−
(
2
⋅
0
)
=
6
x
−
0
=
6
x
=
6
or
(
6
,
0
)
We can next plot the two points on the coordinate plane:

Now, we can draw a straight line through the two points to graph the line:
graph{(x - 2y - 6)(x^2+(y+3)^2-0.035)((x-6)^2+y^2-0.035)=0 [-10, 10, -5, 5]
