Question 768129: The sink now has 12 ounces of water. The drain is very slow, so water is dripping out of the sink at the rate of only 3 ounces per hour. Consider how much water is left in the sink and how much time has passed from now. Write the equation linking them. What is the x/y intercept?

You can put this solution on YOUR website!
x for time passage and y for ounces water in the sink. Unit for x is hours, and for y, ounces.
y=12 when x=0.
Slope is -3.

That is enough data to write the slope-intercept form for the line equation.
