A) to find the difference you have to subtract one from the other (53-(-41)=91)
b) 15
Im pretty sure it’s going to be a, because when you divide by the -6 you’re supposed to switch the sign
Is there an option for (14,8)? It's rise over run
Shifting in the y direction is as simple as adding the shift, ie.,
f(x) = x+4.
In the x direction it is trickier because then you have to replace x by (x-a) where a is the shift to the right... (but that wasn't asked here).
