A BMW car on a truck weighs 20 tons plus 1 ton per cubic yard of x cubic yards of spares that it carries. The total weight of a truck with BMW is: f (x) = x + 20. How will the graph of this function change if the BMW weight is changed to 15 tons? The line will shift vertically up by 5 tons. The line will shift vertically up 15 tons. The line will shift vertically down by 5 tons. The line will shift vertically down by 15 tons.

Kianna Fitzpatrick · Answer 1

Using f (x) = x + 20 the y - intercept = 20

changing the weight to 15

makes the equation f (x) = x + 15, making the y intercept 15

which moves the line vertically down by 5 (20-15=5)

The line will shift vertically down by 5 tons.
