Answer:
y=2
Step-by-step explanation:
2y + 8y - 20 = 5 (y -2)
Combine like terms
10y -20 = 5(y-2)
Divide by 5
10y/5 -20/5 = 5/5(y-2)
2y -4 = y-2
Subtract y from each side
2y-y -4 =-2
y -4 = -2
Add 2 to each side
y-4+4 =-2+4
y =2
1.) (-18, -20) (18, 16)
m= 1
2.) (-7, 14) (-11, 4)
m= 5/2
3.) (-5, -4) (3, 9)
m= 13/8
4.) (13, -8) (-9, -1)
m= -7/22
