Answer:
Step-by-step explanation:
In the equation y = mx + b, which is the form Ingrid's equation is in, the m stands for the rate of change. If the water level is decreasing, the rate at which it is decreasing is what goes in for m. The "b" of that equation indicates the starting height of the water, which is 170. The equation should be:
y = -4x + 170, negative because the water is decreasing.

Set up the direct proportion:
Cross multiply (you can reduce first if you prefer):
Divide both sides by 360,000 to isolate x:
You're paying $20,460 in tax on that $930,000 house.
Can't solve without the table
50 multiplied by 56 = 2800
