A 600-ft tall building is represented by a 30-in. tall model.
Using the same scale, what would be the model size of a
380-ft tall building?

First, find the scale factor by dividing the first building's real-life height by its model height.

Now, we'll write an equation to find the model height of the second building.

Here is an equation where represents the real-life height of a building, represents the scale factor, and represents the model height of the same building.

Fill in the information we already know.

Divide both sides by .

So, the model height of the second building is inches.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
