So right of the bat the equation we know from what's given is y = 2x (+b)
we gotta find out what b is
so we plug the coordinate in
3=8+b.
b=-5
so we put all the pieces back together to get
y = 2x - 5
If you are going from a larger unit to a smaller unit, you multiply. If you are going from a smaller unit, you divide
Divide 22 by 2 to get "c" isolated.
