Answer:
y intercept at y = 1
Step-by-step explanation:
recall that for a linear equation expressed in slope-intercept form,
y = mx + b, where
m = slope and b = y intercept
in our case, y = -2x + 1, comparing this to the general equation above, we can see that clearly slope, m = -2 and y-intercept, b occurs at y = 1
Hope this helps!
The function can be expressed as a rational function is 
.
We have to determine
Which of the following is written as a rational function?
According to the question
A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.
A rational function can be expressed as;
Then,
The required rational function is expressed as;
Where p(x) is (x-5) and g(x) is 3x.
Therefore,
The function is,
Hence, the function can be expressed as a rational function is .

To solve for the time it takes to travel a certain distance at a certain speed, use the formula,
time = distance / speed
Given that the entire journey takes four hours, add up the time it takes David to row upstream with that of him travelling downstream. This is mathematically represented as,
total time = time upstream + time downstream
4 = 3/(x - 1) + 3/(x +1)
Solving for x in the equation gives 2. Thus, David's speed in still water is 2 miles per hour.
