Using implicit differentiation, it is found that the height of the pile is changing at a rate of 0.1415 feet per minute when the pile is 2 feet high.

The slope-intercept form: y = mx + b
(m - slope, b - y-intercept)
We have y = -2. It's the slope intercept form where m = 0 and b = -2.
y = -2 → y = 0x - 2
Y=2/3x-7/3
Hope this helps
We can simply observe that.
- 0.777... is rational, because it is a number with infinite but repeating decimal part.
- 1/3 is rational, because it's the division between two integers
, so this is rational as well.
Since the product of two rational numbers is always rational, we have that

are all rationals, since they are the product of two rationals.
On the other hand, we have

and thus

which is irrational.
