A coal car on a train weighs 30 tons plus 1 ton per cubic yard of coal x that it carries. The total weight of a coal car is: f(x) = x + 30. How will the graph of this function change if the coal car weight is changed to 26 tons?

The line will shift vertically up by 4 tons.

The line will shift vertically up 26 tons.

The line will shift vertically down by 4 tons.

The line will shift vertically down by 26 tons.
