Answer:b is the right choice hopefully dont be mad if it is wrong
Step-by-step explanation:
Y=7x+3
They are parallel so the slope is the same and plug in the two coordinates to get the y intercept. This gives you y=7x+3
Opposite angles in a parallelogram have to be equal so
3y=66
y=22
AB and EF
BC and FD
AC and ED
C, i think you forgot an x
(x+11)+(x-7)
x+11+x-7
x+x+4
2x+4
