Answer:
Step-by-step explanation:
The first step will be to make y the subject of the formula, by multiplying both sides of the equation by -1.
y = x - 1
This is simply the equation of a line with a slope of 1 and y-intercept (0,-1)
To determine the three points that solve the equation, we can let x be;
0, 1, 2
When x =0, y = 0-1 = -1
When x = 1, y = 1-1 = 0
When x = 2, y = 2 - 1 = 1
Therefore, we have the following three sets of points that can be used to graph the given linear equation;
(0, -1)
(1, 0)
(2, 1)

Answer:
The function that models the depth of the hole in feet over time in hours is .
Step-by-step explanation:
According to the statement, the variable to be modelled is the depth of the hole, which decreases whereas is filled. Under the assumption that the hole is filled at constant rate, we obtain the following expression:
(1)
Where:
- Current depth of the hole, measured in inches.
- Initial depth of the hole, measured in inches.
- Filled level, measured in inches.
- Filling time, measured in hours.
- Time, measured in hours.
If we know that ,
and
, then the function that models the depth of the hole is:
The function that models the depth of the hole in feet over time in hours is .
