Ver a 45-day period, the amount of propane in a tank that stores propane for heating a home decrease from 500 gallons to 344 gallons. 1. Use a graph or the slope formula to show the average rate of change in the amount of propane used over the 45-day period.
2. Show all work.
3. Explain what your solution represents in the context of the situation.

3,000,540

step-by-step explanation:

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
