Hi Brenna

b is where the line crosses the y axis. You can see this by picking a any number you would like to use for "x." Double it and you have found the y. If you pick x = 0, you will see that y crosses the y axis at )! Cool huh? You can use negative numbers for x, or even x with an exponent and you will never see y crossing the y axis again - only at 0!
