Graph:
x
+
2
y
=
8
The x-intercept is the value of
x
when
y
=
0
. The y-intercept is the value of
y
when
x
=
0
.
To get the x-intercept, substitute
0
for
y
.
x
+
(
2
⋅
0
)
=
8
x
=
8
The x-intercept is
(
8
,
0
)
.
To get the y-intercept, substitute
0
for
x
.
0
+
2
y
=

y
=
8
Divide by
2
.
y
=
4
The y-intercept is
(
0
,
4
)
.
You now have two points on the line. You can plot them and then draw a straight line through the points.
