Step-by-step explanation:
Slope of line is given by the formula:
Line 1:
The change in coordinate is zero.
Therefore slope of line 1 is .
Line 2:
Change in coordinate = -4
Change in coordinate = 3
Slope =
Line 3:
Change in coordinate = 4
Change in coordinate = 3
Slope =
Line 4:
The change in coordinate is zero.
Therefore slope of line 4 is .
Line 5:
Change in coordinate = 7
Change in coordinate = 3
Slope =
Line 6:
Change in coordinate = -7
Change in coordinate = 3
Slope =
Line 7:
Change in coordinate = 0
Slope = 0
Line 8:
Change in coordinate = 0
Slope = 0
Line 9:
The change in coordinate is zero.
Therefore slope of line 9 is .
Line 10:
The change in coordinate is zero.
Therefore slope of line 10 is .
Line 11:
The change in coordinate is zero.
Therefore slope of line 11 is 0.
Line 12:
The change in coordinate is zero.
Therefore slope of line 12 is .
