Step-by-step explanation:
Completing table 1)
Given the function
y = -3x+2
put x = 3
y = -3(3)+2 = -9+2 = -7
so (x, y) = (3, -7)
Given the function
y = -3x+2
put x = 1
y = -3(1)+2 = -3+2 = -1
so (x, y) = (1, -1)
Given the function
y = -3x+2
put x = 0
y = -3(0)+2 = 0+2 = 2
so (x, y) = (0, 2)
Given the function
y = -3x+2
put x = -1
y = -3(-1)+2 = 3+2 = 5
so (x, y) = (-1, 5)
So the table becomes
x y = -3x+2 y (x, y)
3 y = -3(3)+2 -7 (3, -7)
1 y = -3(1)+2 -1 (1, -1)
0 y = -3(0)+2 2 (0, 2)
-1 y = -3(-1)+2 5 (-1, 5)
The graph of the equation y = -3x+2 is also attached below.
On the diagram, the red line represents the y = -3x+2 line.
Similarly,
Completing table 2)
Given the function
y = 2x+4
put x = 0
y = 2(0)+4=0+4 = 4
so (x, y) = (0, 4)
Given the function
y = 2x+4
put x = 1
y = 2(1)+4=2+4 = 6
so (x, y) = (1, 6)
Given the function
y = 2x+4
put x = 2
y = 2(2)+4=4+4 = 8
so (x, y) = (2, 8)
Given the function
y = 2x+4
put x = -1
y = 2(-1)+4=-2+4 = 2
so (x, y) = (-1, 2)
So the table becomes
x y = 2x+4 y (x, y)
0 y = 2(0)+4 4 (0, 4)
1 y = 2(1)+4 6 (1, 6)
2 y = 2(2)+4 8 (2, 8)
-1 y = 2(-1)+4 2 (-1, 2)
The graph of the equation y = 2x+4 is also attached below.
On the diagram, the blue line represents the y=2x+4 line.
