Y is equal to ..., I'll do a new example, let's try Y is equal to negative 3X so once again, let me do my X and my Y when X is equal to 1, Y is equal to negative 3 times 1, which is negative 3 when X is equal to 2, negative 3 times 2 is negative 6 so notice, we multiplied, so if we scaled, let me do that in the same green colour if we scale up X by 2, it's a different green colour but it serves the purpose we are also scaling up Y by 2, to go from 1 to 2, we multiply by 2 to go from negative 3 to negative 6, you're also multiplying by 2 so we grew by the same scaling factor, and if you want to get the other way
