Answer:
Explanation:
Slope intercept form
m=slope
c= intercept
1) y= -x + 6
2) y=7x + 6
3) y= -3/4x + + 3
4) y= -2/5x - 1/5
5) y= -x + 20
6) y= -7x + 8
7) y= -3x + 3
8) y= -2/5x -2
Line 1 and 5 are parallel because both have the same slope of -1
line 4 and 8 are also parallel as the their slopes are -2/5
