Answer:
y = -1/4x +4
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
-2x-8y = -32
Add 2x to each side
-2x+2x-8y =2x -32
-8y = 2x-32
Divide each side by -8
-8y/-8 = 2x/-8 -32/-8
y = -1/4x +4
The cost of water would be $615 as he needs 3 acre-feet of water for 205 acre/ft
Given that y varies directly with x in the above table, if the value of x is 5, the value of y is 15.
<h3>How to calculate direct variation?</h3>
According to this question, a 2-column table with 5 rows is given.
- Column 1 is labeled x with entries 1, 3, 6, 9, 12
- Column 2 is labeled y with entries 3, 9, 18, 27, 36
If y varies directly with x, the mathematical representation is as follows:
y = kx
Since y = 3, when x = 1
3 = k × 1
k = 3
The relationship between x and y is as follows: y = 3x
Therefore, if the value of x is 5, the value of y = 3 × 5 = 15.

I think it might be experimental probability:)
