Q.
Which ordered pair is a solution of the equation?
y
=
2
x
+
5
y = 2x + 5
y
=
2
x
+
5
Choose Ordered Pair:
Choose an ordered pair to test. Let's try
(
1
,
7
)
(1, 7)
(
1
,
7
)
.
Substitute x:
Substitute
x
=
1
x = 1
x
=
1
into the equation
y
=
2
x
+
5
y = 2x + 5
y
=
2
x
+
5
.
y
=
2
(
1
)
+
5
y = 2(1) + 5
y
=
2
(
1
)
+
5
Calculate y:

5
y = 2 + 5
y
=
2
+
5
y
=
7
y = 7
y
=
7
Check Solution:
Check if the ordered pair
(
1
,
7
)
(1, 7)
(
1
,
7
)
satisfies the equation. Since
y
=
7
y = 7
y
=
7
, the ordered pair
(
1
,
7
)
(1, 7)
(
1
,
7
)
is a solution.
