Step-by-step explanation:
Explanation:
Graph:
y
+
x
=
−
5
Rearrange to standard form:
A
x
+
B
y
=
C
.
x
+
y
=
−
5
We only need two points to graph a linear equation. With the standard form, we can easily determine the x- and y-intercepts, and then plot them.
X-intercept: value of
x
when
y
=
0
Substitute
0
for
y
in the equation and solve for
x
.
x
+
0
=
−
5
x
=
−
5
The x-intercept is
(
−
5
,
0
)
.
Y-intercept: value of
x
when
y
=
0
.
Substitute
0
for
x
and solve for
y
.
0
+
y
=
−
5
y
=
−
5
The y-intercept is
(
0
,
−
5
)
.
Plot the x- and y-intercepts and draw a straight line through the points
