Answer:
One inch represented 3 feet in the first scale, but now 1 inch now represents 4 feet in the second scale.
Step-by-step explanation:
We need to graph this equation:

Its solutions are the points through which it graph passes. Since it's a linear equation its graph is a straight line and we only need two of its points to draw it. But before graphing let's re-write the equation. We can substract 16x from both sides:

And we divide both sides by 2:

So now with this equation if we pick two random x values we'll get their corresponding y values. This way we'll find two points that are part of the graph which is the line that passes through both. We can begin with x=0:

So the first point is (0,150). Then we can take x=10 and we get:

So the second point is (10,70). Then the graph is the line that passes through points (0,150) and (10,70). In order to represent it

Hi, there!
I'm not sure what you want to solve in these equations. Please provide me with more details. I am sorry if you were looking for answers to the question, but I simply do not know what you are asking for.
Thanks!
