Hey there!
Let's write this as a system of equations.
m+b=22
b= 4m-3
Let's plug our value for b into the first equation and solve for m.
m+4m-3=22
We combine like terms.
5m-3=22
We add 3 to both sides.
5m=25
We divide both sides by 5.
m=5
Therefore, Maggie is 5 years old.
I hope this helps!

Answer:
slope=m=4/9
(x',y')=(5,14)
(x",y")=(-4,y)
we have
m=(y"-y')/(x"-x')
4/9=(-4-5)/(y-14)
4y-56=-81
4y=-81+56
y=-25/4
