Answer:
A
Step-by-step explanation:
If you divide 180 by 60 you can see that they send 3 texts a minute after you divide 45 by three and see that they have 15 minutes left the Number line diagram shows the amount of time and texts she can send.
They do not equal each other
the -a and +a make them not equal
y=-3x+8
y=mx+5, m=-3, x=1, y=5
5=(-3)(1)+b
5=-3+b
8=b
