Question # 9
Answer:
The graph of [tex]y = 2x-1[/tex] is shown and attached below.
Step-by-step explanation:
Considering the function
[tex]y = 2x-1[/tex]
Putting x = 5
[tex]y\:=\:2\left(5\right)-1[/tex]
[tex]y = 9[/tex]
(x, y) = (5, 9)
Putting x = 2
[tex]y\:=\:2\left(2\right)-1[/tex]
[tex]y = 3[/tex]
(x, y) = (2, 3)
Putting x = 0
[tex]y\:=\:2\left(0\right)-1[/tex]
[tex]y = -1[/tex]
(x, y) = (0, -1)
The graph of [tex]y = 2x-1[/tex] is shown and attached below.
Question # 10
Answer:
The graph of [tex]y = 3x-7[/tex] is shown and attached below.
Step-by-step explanation:
Considering the function
[tex]y = 3x-7[/tex]
Putting x = 4
y = 3x - 7
y = 3(4) - 7
y = 12 - 7
y = 5
(x, y) = (4, 5)
Putting x = 1
y = 3(1) - 7
= 3 - 7
= -4
y = -4
(x, y) = (1, -4)
Putting x = 0
y = 3(0) - 7
= 0 - 7
= -7
y = -7
(x, y) = (0, -7)
The graph of [tex]y = 3x-7[/tex] is shown and attached below.
Question # 11
Answer:
The graph of y = -4x + 8 is shown and attached below.
Step-by-step explanation:
Considering the function
y = -4x + 8
Putting x = 4
y = -4x + 8
= -4(4) + 8
= -16 + 8
= -8
y = -8
(x, y) = (4, -8)
Putting x = 2
y = -4x + 8
= -4(2) + 8
= -8 + 8
= 0
y = 0
(x, y) = (2, 0)
Putting x = 1
y = -4x + 8
= -4(1) + 8
= -4 + 8
= 4
(x, y) = (1, 4)
The graph of y = -4x + 8 is shown and attached below.
Question # 12
Answer:
The graph of y = 7 - 2x is shown and attached below.
Step-by-step explanation:
Considering the function
y = 7 - 2x
Putting x = 7
y = 7 - 2x
= 7 - 2(7)
= 7 - 14
= -7
y = -7
(x, y) = (7, -7)
Putting x = 5
y = 7 - 2x
= 7 - 2(5)
= 7 - 10
= -3
y = -3
(x, y) = (5, -3)
Putting x = 3
y = 7 - 2x
= 7 - 2(3)
= 7 - 6
= 1
y = 1
(x, y) = (3, 1)
The graph of y = 7 - 2x is shown and attached below.
