when x=2 in the equation y = 2.7x + 6.3, why is it that it is not twice as high when x = 1?

Because of the + 6.3. If that wasn’t there, then it would be twice as much, but because you have a fixed number being added to the multiplication, then it ends up the way it is.

in this equation your only doubling the first number and then adding the 6.3.
think about it this way
5
10
10 is 5 x 2 right?
so 5 and 10 have a relationship where if you multiply the same number times both, they will always be one half.
5×5 = 25
10 x 5 = 50
25 is half of 50
now if you add the same number to them, they loose that relationship.
5 + 5 = 10
10 + 5 = 15
I hope that makes some sence instead of confusing you more.

Because of the 6.3
2.7+6.3=9
5.4+6.3=11.7
2.7 is half of 5.4

You are doubling the 2.7, not the 6.3 and 2.7. 6.3 is constant and 2.7 is attached to the variable…
